trying to make this follow site rules. i really need help.

the previous owner of my jeep straight piped the exaust, and all though it sounds good, its illegal and i need to change it.

i want to know if there any possibilties of it doing harm to the engine since he cut the cat off?
and if i buy a flowmaster 44 kit will i be good to go?

stupid question... but is it bad to rev my engine? i do it occasionally just messing around, and i had to do it alot when my battery died to get it to autozone, so just wondering.... because my friend told me today its messes it up bad...

 

No harm

 

Go to www.performance-curve.com and go to the exhaust part.. They are cheap and you can get everything you need on the cheep trust me. Alot of ppl will recomed the site....
As far as the muffler I like the 44. Check out one of my threads its about glasspacks. And flowmaster 44's.. And also I rev. Mine to...and some time I floor it.. I try not to. But I'm not to. Sure about it...but if you have more questions about muffles I can deffently help you out and exhaust questions to

 

Note forgot to add. Cut off cat is no harm to your engine..

 

seriously? if so im just gonna leave it. its not bad at all, but i read somewhere that is confuses the computer or soemthing... got worried

 

i was literally looking for this link while posting this, def ordering from them if i decide to change it. thanks for the help bro

 

There is alot of misinformation floating around about cat converters.

It will not cause harm, however its a Federal Regulation, not state. Our sport is already having enough trouble as is with people forcing trails to be closed, don't give more reason for them to be upset.

 

Naw it won't confuse you computer. BC there are no sensors on our cats. So no issues... And your welcome man anytime. And I always leave that lil website when ever some one has an exhaust question its a great place and its good deals.

 

ohh yeah big time.. I got cussed out by a guy driving a pruis BC of my xj....dont add fuel to the fire for them. Pick up a 32$ highflow cat

 

Some have them after the cat. If you leave it plugged in but not in the exhaust itself the CEL will stay off.

 

Haha not on my 93... But that's a sneaky lil trick lol

 

It lookes like you have a 84-95 that has no O2 after the cat. That is the only time it is harmful is when the computer is reading how the cat is doing and adjusting the fuel to air mix based on that reading 96-01. Rev it only when it is warm and never hit the rev limiter witch I think is 5,500.

 

I've only let mine hit 4500.. And I do believe it starts at 5500

 

Yea, go here, buy a cat, muffler, and tail pipe all for under 200. Install is a breeze. Save yourself the trouble of dealing with tickets and fines

 

some models have an O2 sensor before and after the CAT, the one after "reads if the CAT is working properly", but no harm if you remove the CAT. unless you hate the planet. haha
