Hi flow cat

Re: Hi flow cat

Plus your y-pipe is 3 inch anyways, so its bottlenecking anyways... yeah..

correct. The exhaust manifold (primaries) are very small (like 1.25"?). Then the header 2 y-pipe is like 2.75" on both. Then the Y turns into like a 2.25" right before it merges. Then the y-pipe turns into a 3" where it connects to the 3" cat (and the stock cat inlet is 3"). Its alot of bottlenecking.
But Flow speed and CFM is really what matters.

Even if I still had the stock catback ie 3 d still use thinch cat and 3 inch spipe, you can just weld a 3inch catback to it later on and be finished.

me too

Re: Hi flow cat

So what you guys are saying is i should put on a 3in/3out cat then a 3in S-pipe. then a reducer pipe right after the s-pipe to reduce it back down to 2.25in. right?
