Thanks for the video and dyno results!

Now, in your opinion (since it is hard to tell in the video) is it much louder than the stock set up? Deeper?

thanks again.

The sound is hard to tell in the video because it's up at the engine, but it is definitely louder. It's not obnoxious though, just deeper, meaner sounding.

In the video, was the car completely stock with the exception of the headers?

Is tuning necessary after installation?

Sounds great. Thanks for the hard work to get these things on the market. I'll be looking at getting a set in the near future. Any plans for a group buy?

The car had the joe Z intake tube and an exhaust. There wont be any tuning necessary plus there really isn't anything tuning wise out there except for the AEM with some custom mods by elite. The only thing you will need is the provided parts to keep the 02 sensors happy.

+1 on group buy!

Any way you could scan the dynos I'd love to print them out.

Also was this run on 93 octane?

When will these be available for sale?? Will you ship to Puerto Rico?

They are available on Sikky's website

A group buy sounds fair...

+1 on the group buy

Nice!!!!!! I love that it's my car. She sounds mean. Great job sikky! The car was run on 93 octane.

Hey Jason,

I don't suppose you will be anywhere near Baltimore tomorrow? I would love to hear that beast in person.

So...I had the pleasure of riding around in Jaslapp's car today. WOW!!! That thing is wicked. It is definitely meaner than stock, but the sound deadening of the car makes it quite bearable with the windows up (Of course everybody has a different tolerance to noise). I took a video on my camera, which didn't turn out very well. I'll try posting it. I almost don't want to because it absolutely does not do the real sound justice. We hit a rainstorm midway through the video, and you can hear the rain on the windshield more than anything. Sorry, I wish I could have provided better audio.

post that shit.

good man. windows down really kills any video because all the camera picks up is mid freq wind noise. sounds good, now the car just needs a k&n intake then it will have some serious anger issues.

Gymkata, objectively though was there a big diff? Is power jump worth the extra db in sound? How I wish Akarapovic will make exhausts for our baby.

I definitely think it is worth the extra sound. I haven't ridden in an ISF with just the JoeZ exhaust, but according to Jaslapp, the exhaust makes more of the noise than the headers do. The Sikky headers with JoeZ exhaust are only a little louder than with just the JoeZ exhaust, but provide a more savage crackle. It is hard to describe.

I rode around with Jaslapp for about 30 minutes. At first I thought it might be a little loud for daily driving, but we were driving with the windows down. With the windows up, I could definitely live with it and love every minute of driving. Other motorists will definitely know you are there though, as it is much louder outside the car. The sound is absolutely intoxicating.

The important thing is the car isn't that loud in the cruising RPM band (1500-2500). The sweet aural intoxication will spring to life the second you put the petal down though.

As far as a power jump, it felt faster than stock. I was a passenger though, and it is difficult to determine when you aren't driving. Plus I think the meaner sound makes it feel even faster.

The Sikky headers will be my next mod...before an exhaust. Dollar for dollar, I think that is the biggest gain you can make. I probably won't be doing this anytime soon though, as I have to finish building my house first and see how much spare change I have left over.

I'm glad you enjoyed the ride. I was gonna take you around the back roads some more but it started raining.

i ordered a set of headers. and sikky called me today to confirm that i have been charged 500 for a deposit until they ship. its nice to deal with a company that notifies its customers when they order things. i ordered the joez carbon fiber exhaust tips last week from carson toyota.... not a peep. and i have been charged. when i ordered my exhaust last year i called them after 2 weeks, only to have them tell me that they didnt have any in stock and they weren't even being made yet because of lack of parts. i dont want to rag on joe, its fine on his end, but they couldnt even let me know what was or wasnt happening. i just hope sikky has these made in 3 weeks like i was told so i can get them on.

How come you didn't wait to see the results from the elite headers??

There are some serious issues with that torque curve tho..... That is not normal at all! I have dynoed 3 F's and that is not normal... In any mode...

How come you didn't wait to see the results from the elite headers??

according to andy, the elite headers require that the engine be removed. it has been stated from sikky that the engine does not have to be removed to install them, it can be done from underneath.

this is a huge factor. especially since i take joy in doing things myself, i will be putting on my headers. this means i have to do alot less work.

Actually on clublexus Elite posted this:

The Elite Headers will have a dyno sheet and video to back them up!!! :) Oh and PS.... They are mocked up on Splats car right now! I was gonna post pics but i LOST MY CAMERA.. I'm going to sleep and will find it in the AM. Oh yeah and we did it without pulling the motor..... SWEET!

I was wrong, we put the prototype headers in by pulling the subframe. It worked very actually.

I have been thinking about this all day and its bugging me... I have looked at all the dyno charts I have here for the F's... I find a few things very interesting... #1 The torque curve is absolutely the WORST curve I have ever seen, it should be flat. #2 The headers gain only 5 HP all the way up to 5200 rpm ish... That seems really odd because you would think the power increase would be linear..

Look at the difference in the torque curve of splats and Sikky's. It just doesn't add up..

At what rpm does the F get "on cam"? Just like a turbo car, the more agressive the cam profile, the more important your exhaust path is. IE, you are going to be seeing larger increases when the car is on the more agressive cam profile.

Also, the torque curves are similar, it's just the different scaling on the graphs that is exagerating the differences. You can see two small peaks in the torque curve on your DD dynno, but the two peaks on the other graph are much more visable due due the differences in scaling.

I bet the funky torque curve has more to do with the 'micro-processor' than the headers themselves. We need to see an overlay of that dyno run with the AFR. . .

I am sure the "micro-processors" are in fact just O2 simulators to keep the check engine light off. O2 voltage is typically not taken into account for WOT operation anyways.

The problem with that is my torque curve never drops in the middle....... his drops 20-30 ftlbs in that valley... That should not happen....

Let's hope your fab skills are sharper than you observational ones ;)
On his dyno, the drop form the first peak, to the bottom if the drop is 10lt/lbs., it then rises an addiitonal 25wtq to peak, this equates to about a 15wtq difference between peaks.
On your graph, the decrease is a little less than 10wtq (hard to tell with the much different scaling/graphing), but indeed increases the same amount form peak to peak (15wtq).
There may be a couple ft/lb difference, but thats is hardly a big deal, especially since long tubes could certaily effect the powerband before/near peak torque ;)
Ofcourse, why would you have something negative to say about a competing product ;)

has anyone noticed that the before dyno, which would have had the car without headers and microprocessor, had an almost identical profile to the torque curve? to me this just looks like dyno software.

This says it all, I don't think we need to say much more. But I will add that this really comes down to the difference in dyno's. The dynapack is far more sensitive and will show fluctuations more than the dynojet. The mass of the rollers spinning tends to smooth dyno plots out and will not show the fluctuations that are present as clearly. Also, for comparison sake this setup has no tunning software or AEM ems setup on it. This factor pretty much eliminates the validity of a comparison between the two cars and there dyno plots.

My car has no AEM ems hooked up to it yet. Its running the factory ecu. And its an honest mistake that im sure Andy will own up to (as in miss reading the dyno plot). Nothing more nothing less.

I'm sure you are right.

The problem with only being able to type what you want to say is that most of the time we make it short and sweet, and when most people read something they take it in the worst context possible and think it is an attack on them when it is only a statement:(. This is a big struggle to deal with in my office when communicating via email.

I think that we are all just making sure we understand everything and are trying to get the answers that are important to us.

The only thing Splats car has extra is the ported intake.... There was no tuning done to that car.

On another note after dynoing our headers I now see that they do affect the torque curve and after scaling our graph the same as yours, they are similar. I still don't understand why you scaled it that way... but it is a valid curve.

I visited an empty parking lot this evening and decided to have a little fun. This car really needs some 275's in the back! Anyway, this is what the car sounds like with the SIKKY headers and the PTS JoeZ exhaust. I love it! I have about 400 miles on the headers now with no CEL and nothing but smiles. Thank you SIKKY and JE! :thumbup:

sweet !!! :eek:

Caymandiver, that was great!The numbers are already impressive I was just waiting to hear more comments on how it sounds like with the sikkys. Nice and angry. I like the higher pitch as a result. By the way, was that the rev limiter cutting in?
Another order coming up.

Yeah that is the rev limiter kicking in. In person these headers sound even better. I feel like I'm driving a new car again. Lol

Last night, four ISF's from the Baltimore/Annapolis area met up. I had Jaslapp give my wife a ride in his car with the Sikky headers and JoeZ exhaust. When my wife stepped back out of the car she had an ear to ear grin. I asked her if she like the way it sounded and if it would be ok for long daily driving, and she just giggled and nodded yes.

Thats what I like to hear!!!!!!

Good to hear wife approved....

Out of curiosity, Do these LT's weigh less than the stock logs..?? MB did this same exhaust set up on my E63 and it is by far the weakest point of the engine. Too bad the people making LT's for the 63 want an arm and a leg, almost literally...

The headers are 1 lb lighter per side.

Cayman, what are your thoughts on passing emissions in VA?

Cayman, what are your thoughts on passing emissions in VA?

I just had my emissions done about a month ago with the JoeZ exhaust. All they do is plug into the OBD2 port and look for error codes and since the Sikky Headers come with a clever simulator the car is Error free and will pass emissions.

Son, you're not making it easy for me to save money. :p

I really don't remember if my STi had the sniffer test. I didn't pay attention because I had a high flowing cat. The place I go to in Hernandez has a guy thats really into cars, so the entirety of the test was us talking about cars.

Oh, btw, my PM and I went lunch and I let him "merge" onto the toll road. After a couple chirps of 1st and 2nd I think I have another F buyer ;-)

that sounds phenomenal. what did you use to record it? whatever it was did a great job on capturing the audio without clipping/distorting. Can you use the same camera and get some interior noise level clips? same exact sequence - startup, idle, idel revs, launch, cruise. then repeat with windows down?

Hi, I'm new to the forum and thinking about picking up a used 08 is-f and installing a joe-z exhaust and sikky headers. So with the two mods, I don't ever have to worry about taking any aftermarket parts off for emissions? Because that would 100% deter me from getting the mods.

Btw caymandiver75, I think I might have seen you in Columbia roaring by on 29. The only reason I presume is because the is-f sounded nothing like stock. I roll down my window periodically when I drive near one, haha. Are you in that area? I frequent EC and Columbia regularly.

Are you a Maryland or Virginia resident? I can't speak for Maryland, but here in VA, they just hook the car up to the OBD2 port and scan for emissions codes.

You probably did see Jaslapp1. I believe he works up that way.

I'm in the suburbs of Baltimore. I am having a daily mental debate of trading in my dd 05 g35 cpe and a beater 04 accord for the is-f. The G35 is in mint condition and the accord is the work horse. Financially, not wise but damn... the is-f is consuming my mind...

shoot... I have already been reading up on the diys already. I refuse to buy a car that I can't do most of the maintenance on.

I hand an accord, then a G then the ISF too :D Do it you wont regret it :D

Has anyone received information from SIKKY on ship dates for the first sets of Headers, everyone is probably bugging the hell out of him, I can't get them on the phone. Of course we are anxiously awaiting.

i talked to them this week and he is saying a delay again probably another 3 weeks or so..maybe longer who knows

aggravating i know

That would be me :D. I live in woodbine and work in columbia. I use to live in EC so a lot of my friends live in that area. You should pass emissions no problem. I'll find out in a few months I should be getting a notice to go to emmissions soon I believe. If you ever want to check her out let me know!

double i know im almost ready for a refund

I know it can be discouraging but give them some time guys. I agree if they said 3 weeks it should of been three weeks but sometimes things get held up when it's out of your hands. I know they don't do the PCing they send it out to another place to do it. If that place holds them up there isn't much Sikky can do besides ask them to hurry up. The product is well worth the wait trust me guys. I'll see if there is anything I can do to speed the process up.

Oh close to 4,000 miles on the headers no problems :cool:

Thanks for the offer! I'll have to make some time sometime soon. I'll be keeping the G but waiting for a "steal" on a used is-f.

Hello guys and gals, First of all we would like to thank everyone for there patience. Just to give a better explanation of what the hold up is......

All our delays have stemmed from the one and only step that we have to outsource. The ceramic coaters have been very backed up and the headers had been sitting there in line just waiting for coating for an agonizing two weeks before they started. We were told an eta that they were not able to meet and apologize for the delay this has caused. Due to the fact that we have tested with this coating from the beginning and its quality is second to none we decided to leave them in line and continue to wait. The thought definitely crossed our minds to send elsewhere, but in the end we believe this is for the best. In keeping with our business model and our motto "quality being #1" we did not want to rush to a new and untested coating facility just for profits or to sell more headers. Hope everyone can understand, and we can assure you it will be worth the wait. The most recent updated time for shipment will be end of next week/early following week depending on when you ordered. We will be drop shipping many headers directly from the ceramic coaters to save a day or two depending on your location. Again, thanks for the patience and we apologize for the delays.

=) Can't wait for mine..... Drop Ship mine FIRST

sounds like a beast.
