Hey I am currently using the tanabe SMR exhaust system, but i decided to get the HKS carbon TI. I was wondering if anyone can help me decide between the turbo version or the n/a. I was planning to put a comptech supercharger on it, and was wondering if a three inch piping would be useful or just a waist of money.

 

if you go FI 3in would not be a waste of money

 

it's a bit much for a N/A engine, you'll have no available backpressure, which would hurt your lowend power

 

^yep yep

if your N/A biggest i would do is 2.75 but thats still pushing it for me i think

N/A=2.5 no larger than that

 

No reduction in backpressure does not hurt power and torque. It's a myth. Reduction in exhaust velocity is another story.

 

i didnt know they made the carbon ti for the s. there website only lists a few and the s isnt one of them. would be nice to know where your getting yours at so i can jump on one as well.

 

if he gets it, it will be the muffler with custom piping
