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?

Just when you hammer it or at a specific RPM? If it's a specific RPM I'd have to say fuel filter.

Jeepster2137

Usually when I hammer it. Does fine if I accelerate slowly.

Being that a fuel filter is only $10 or so, I'd change that first. Unless you changed it in the last... 20k miles I think is recommended?

Jeepster2137

It problt been more than 20k miles since replace. I'll pick up one tomorrow and hopefully it helps. Thanks!

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

Also check the TPS for dead spots.

x2 on that, I had the same problem and cleaning my TPS, and IAC valve seemed to solve it. Im not quite sure what did it but she runs fine now lol

Anybody runnin Flowmaster super 10 muffler...can u use stock piping or not....or should i just do straight pipe from the cat back...

NorCalJeep

Flowmaster makes cat converters now. Just found that out.

Howre u hammering it? If drop the pedal as fast as u can it will do that most likely.

You can use stock piping although iirc the stock after cat is 2.25 id. You'll need an adapter to 2.5 od most likely for the super 10 because I don't think it comes in 2.25. Or you can fill the .25in with exhaust wrap.

will a 99xj exhaust manifold fit my 96 xj?

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.
