free-flow exhaust question

I have a 97 TJ with the 4.0 I-6. I took off the muffler now have nothing from the catylitic conv. back. I am wondering if this is going to harm my engine at all. I like the sound but if it's bad for it then I guess I'll go with some type of cat-back system. Any info would be appreciated. -Ben

Re: free-flow exhaust question

There shouldnt be any damage to your engine by not running a muffler. But Here in Az cops can pull you over if your car is generating "noise pollution" which can be anythingfrom loud stereo to loud engine. Also emissions may nail you for an equipment violation. But like i say it shouldnt hurt the engine

Re: free-flow exhaust question

Be warned removeing exhaust system parts or using to large a exhaust pipe WILL result in insufficient back pressure. Which WILL cause the valves to burn and leak.

Exhaust modes are a good way to increase preformence and do sound cool. But if you take it to far it will hurt your engine. As to your removing exhaust pipe from the cat back. The Cat may produce enough back pressure to prevent damage (don't know for sure).
