Pontiac G8 2008-2010 - G8 Exhaust and Tune...

This was a customer who came to us with a Vararam already installed for the baseline, we then installed headers/cat-back and tuned it.

What kind of exhaust and headers?

Kooks and Corsa

When I have money for headers and a stall, it's coming to see you.

Nice job Steve! Now tell me you can give me better gas mileage with it and I'll have some ammo as to why I need a tune! :P

I'll tell you right now I get much better Gas mileage with my Intake/Long Tubes/Exhaust and tune setup than I did stock. I can easily rip off 26-28mpg on the freeway, when stock it was a challenge to hit 25. I still have DOD active in my tune though...

Man, I am struggling to get 19-20mpg....but it may be how i drive. :D:D

I didn't need to hear this as I have a car that is getting a lot of attention and MONEY. SNL knows this very well. :D

Great gains!

Sounds great, just let us know when you're ready!:cheers:

Actually you will, as the engine will be more efficient and use less fuel being leaned out from the overly safe factory tune.

Great gains!

Thanks!

Very nice gaines there.
Question, where do you plug your wideband, do you install an extra bung or do you run in one of the O2 spots?

Thanks, with headers that have an extra bung we install the wideband there, otherwise we utilize one of the O2 spots.
