Catalytic Converter???

Ok....if anyone hasn't noticed, the exhaust system on the liberty is extremely restrictive. Two pre-cats out the headers, a main cat, then a huge [censored] muffler. Well...I have a few options....I love the borla dual exhaust for the liberty....but..700 dollars no way. I'm cheap lol. So why not go the illegal way? Take the main cat off, 5 hp possibly, and a little more rumble but not too loud. Well, a few questions have been going through my mind. Will my check engine light start goin on because its detecting a change in emissions? Also, will it void my warranty...probably.....damn

Re: Catalytic Converter???

You probably have to leave the cat on for your state emissions but you can go to a more free flowing muffler like the magna flow with good results. The exhaust is already about 3" diameter. Besides if you free up the flow too much you'll decrease back pressure which usually increases HP but only at the top end and you lose low end torque which the KJ seems to be lacking somewhat. Keep the cat,put a magnaflow in.done

Re: Catalytic Converter???

Well if you didn't know about Cats...they really aren't all that great for emissions. Catalytic converters have to run at a certain temperature to work. The thing is, most of them dont' reach this temperature. So until your engine is warmed your catalytic converter doesn't do jack on cutting down emissions.
