Fast Intentions exhaust is here!

I may be wrong about this... but I was watching something on Speed TV, and they had a quick breakdown about what size you want for exhaust. Short version= a car producing 300- 450 HP want to stay at 2.5" ideally, as HP goes up, exhaust diameter goes up. So if that's true, the 3' exhaust would be no benefit, and possibly detriment. Comments?

Maybe this is for the tt version? Need bigger pipes for the forced air?

This is correct, unless you are pushing over 500-525 RWH dual 3" is overkill. Especially if the car is NA or Supercharged. You would suffer low end torque and some mid range power.

Now being turbo or twin turbocharged the 3" will not hurt you at all. In fact it will help you get to a zero PSI back pressure. This is optimal to maximize performance. Turbos do not need any back pressure to make low end torque.

Thanks, Tony

Woah...............intake? How did I miss that one?

I love it when company's make full bolt-ons for a platform. Then you know everything was built to work together and at least in FI's case, for maximum performance. Definitely looking forward to new products.

Either way is fine just let me know. I was hoping to be pretty deep in to the car by Friday night!
