Can anyone suggest any manufacturers that make a cheaper high flow cat? Basically all I've found so far are Magnaflow high flows, which are nice but also a bit pricey. I don't really want to use a test pipe or straight pipe because I'm not too keen on the stank from them, as well as the noise. Looking for someone that makes one in 3", and I'm looking at a power goal of like 250-300 WHP, so nothing crazy.

 

Cats are expensive because they have platinum in them. These precious metals are worth a lot, that's why people recycle them. If you get a cheap generic cat it probably wont have patinum and wont work. Like everything else, do it right the first time instead of wasting your money. Just spend the money on a Magnaflow. I have a 3" and pass Colorado emissions with 1000cc injectors.

 

just put a straight pipe in and dont even run a cat.
