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!thank for the info
did you pass on the dyno with the a/c on with your headers
if i remember i read something about you on the dyno and i think you say you forget the a/c also
but maybe i am wrong
thank friend

I have the same question, must be the lighting.

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.*ahem* - can someone answer my question please?

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.

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.

Emissions inspection in CA
Thanks
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...

CA smog
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
