gutted cat.
The previous owner of my truck gutted the catalytic converter I was wondering if this helps or hurts. I have had people tell me that gutting one frees up the air flow and provides more horse power and I have heard some say that it destroys vital back pressure which provides low end tourqe. I know it is illeagle but it just sounds so good with my flowmaster.

Your right it is illegal. You can find an aftermarket cat cheap, which will help your torque and the environment, through a Downey cat back. You could probably do everything yourself for $250.

I was expecting such
Even if it was not against the law I would not recomend this mod the gains are not worth the effort and if you do not get a performance muffler it sounds like crap. I plan on getting a free-flow cat with hopes that it will not tone down my flowmaster to much.
