So while I was tightening my oil pan bolts yesterday, I noticed something that looks like a miniature muffler right after the down pipe. What in the hell is that? LOL It is all straight pipe after that though. Just curious.

 

Catalytic converter, either hollow it out or replace it with a chunk of pipe, they are way more restrictive than a muffler and will plug up if you don't drive many long distances or blowing smoke alot, get rid of it and let that thing breath!

 

X2 cut that thing out!

 

Look at how much crap came out of my '95 cat. I could tell a big difference with throttle respone and such

 

make sure u dont have to emissions test before u hack it out.

 

Out here in Colorado it's a visual inspection for the cat and a smoke opacity test. Anything over 35% it considered failing.

 

Good point monster12valve... Check the laws first! You never know what BS they might make you have/pass
