Are certain brands of hi flo cats actually better than other brands? Like, do some flow better than others, or are some more effective on emissions than others? What's a good, cheap brand? I guess the reason I ask is simply that when most people talk about their mods, they always make a point of mentioning *which* brand exhaust they have, or *which* header, but those same people more often than not just say they have a hi flo cat.

 

here's a good brand, random technology, i don't know about cheap though, its pretty expensive

 

i got a type x from shmotorsports.com it was like $100 but seems to be pretty good but i cant pas the pa emissions with it
