Anyone know any good systems for about 400$? I was thinking some headers and a high flow cat with a glasspack. I noticed the headers all have about the same shape, just different coatings? What would it change?

So every time I try to accelerate hard the engine start to choke. Could that be from the cat being no good? And there being no good back pressure?

x2 on a fuel related problem. Go get your pressure tested before you change the filter. Its a little bit of a pain to drop the tank. Unless its empty. But for some reason fuel pumps almost always go out right after you fill up the tank. Lmao

Would it mess up my o2 sensor too much to remove my cat until the new cat ships in from Amazon. It is clogged up and is causing rough idle and kick back. It should only be a few more days till it ships in.
