Will I sacrifice low end power with 2 3/8" exhaust (HKS Hyper)?
My car is N/T with AEM Short RAM and I am planning on nitrous and or a turbo in the near future. Thanx

I'm 99% sure that YES. But it won't be all that noticeable. Low end torque isn't all that important when racing anyway, seeing as how your gonna be running over 3500-4000RPM.

'tis it

if you're sure you are going to get a turbo anyway, you'll need that size exhaust, so don't worry too much :)

With the combination of the intake and exhaust the loss of low end will be noticible but not bad, and what ever you lose in low end you'll gain in top end.
