Topic: Pro's and Con's of removing catalytic converter?

[WranglerCOdy]

the smel is bad. i had my cat blow out on me while trail riding. i got home and cut it out to see what happened and there was nothing left.. its all in my flowmaster right now. i welded back in for the time being because i had to drive it home. my plans are to buy a high flow cat and have it welded in. just driving the jeep with no cat sucked. it felt like it was lacking low end torque. and it honestly sounds like whoppity. i recommend flowmaster 40 series to anybody that wants a nice tone to the exaust. but never take off the cat. and the legal area of this subject is very tru. i live in Fl and we have NO emissions. but i got pulled over in Feb. and the cops tryed to convince me i didnt have a full exaust. and me knowing what i had under there i got out of that ticket rather quickly.


just my 2 cents tho.

I have higher end power but no low end. When I try to step on it it sounds as if my exhaust is leaking up near the engine. I can't find it though. I was just curious on the converter question. I always heard of people taking them off so i figured I would ask. Thanks for all the help and info though.

Check teh back side of the exhaust manifold just below cylinder 2 and 3. Thats where mine blew a hole and leaked causing the same problem.

Typical if you have an exhaust leak or no cat.

I have no cat and don't have that prob.

I would say exhaust leak mainly cause the o2 sensor would read improper

a cat shouldn't restrict unless it's plugged.  I have tested lots of cats at work when I get vehicals in for lack of power it's one of the first things I check and we put on a exhaust back pressure gauge and if it's good you don't get any restriction till your extremely high in rpm range witch is usually due to the exhaust system to not the cat!!


and when I say high rpm I mean if you tach it out!! going for a good run with it
