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.

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.

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.

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.
If it was on 29, then you probably saw Jaslapp...Blue, loud and driving fast?
