Well, this goes to show you that all F's are not created equal. We just did a before and after dyno on a ISF that had only 6k miles on the clock and was bone stock when arrived. This car performed very well stock and made a great gain without anything but the headers.

Base line #'s on this car before the sikky header
375 hp and 322 tq

After the Sikky headers
409 hp and 341 tq

It did make slightly more 1 run but we threw that run out.
Here is the video with graph

Yeah the same thing happened to me. We forgot to turn the A/C off, which is how we discovered the 15-20whp difference in power. Anyway you should be good to go now. Keep us posted on how you are liking the headers and I will do the same. Cheers!

Is that a green ISF? Or just the lighting?

Lou

I have the same question, must be the lighting.

*ahem* - can someone answer my question please?

Hello, it can be done in 6 hours or quicker. I would not expect that the first time through though and 8-10 would be more realistic for a first timer.

SIKKY Headers with stock exhaust

Well this is interesting!

So the headers alone will make more power on the IS-F than with a catback exhaust and stock headers. So for those of you out there with families, just not into the whole elevated noise level that come with aftermarket exhausts and willing to spare a few ponies, it looks like the headers alone are a great option. As pleased as I am with the results today, the PTS JoeZ exhaust is going back on the car in the very near future. I miss the sound and will need the additional power this fall if I plan to squeak into the 11's.

I would be sending it to a shop. So a shop should be able to do it in 6hrs right?

James,

I truly appreciate your time and effort with the dynos and sharing the results with the F community. I found the results of the headers and exhaust note quite interesting! Personally, I am not willing to give up horsepower or the amazing exhaust note. I agree that the set up is suited for someone with kids. Do you still hear the cylinder pulses without the JoeZ exhaust?

Kind Regards,

Rachael

Rachael, the cylinder pulses can still be heard, but it's very subdued compared to before. Right now I really miss how the car sounded before with the PTS JoeZ exhaust especially while sitting at a stoplight with the A/C on and also how it screamed towards redline. Aside from the slightly deeper exhaust note, the only way you could tell I have headers on the car now is during cold starts when the engine valves are adjusting.

Now I need to make an appt with JE to get the PTS JoeZ exhaust back on. If they want redyno my current setup on their dynapack, that would be cool too.

James,

Why did you take off your JoeZ exhaust in the first place?

I'm assuming you installed the headers w/ the Joe Z exhaust, dynoed. Then put the stock exhaust on and dynoed again??

Thanks,

I needed to put the stock exhaust back on to pass the VA safety inspection. I figured I would take this time to get more testing done in this configuration before the PTS Joez exhaust goes back on.

Hello, does anyone have ideas whether headers and stock exhaust will pass emissions inspections in CA?

Thanks

Gotcha. Lots of work for a sticker.

In San Antonio there are plenty of places that'll give you a sticker sight unseen

Glad you did it though. I'm planning on getting a set of headers eventually and putting them on with the stock exhaust minus cats/mufflers/and modified y section...

might fail visual though. or go to a performance shop that also does smog checks. they'll "help" you out.

Thanks for the info.

Do you think an average smog only place will know enough to realize that the headers aren't stock?

That's a toss up. I would think the shiny header finish would be a giveaway that they're not stock. Unless the ceramic finish isn't shiny? I don't remember what that looks like.

They are shiny
