I wanna make my truck sound as mean as possible. Right now i have a 40 series flomaster single 2 1/2 out and people are telling me to gut my cat. Would this change the sound at all?

why gut a perfectly good converter? just for more noise??? if you want more noise, get a louder muffler.....

then again, why make it louder at all???

take it off, start stabbing the inside with a pipe, thats what i did, today, periodically dumping out the honeycomb looking shit inside. i was forced to take some action though, listen to this, i just put headers on my s/c 4.3, and melted the inside of the cat at the entrance, crazy huh, i had way too much back pressure there. i didnt get to finish it all, but the amount that i did get done made a very noticable difference.

That chit inside can be real hard, get a long drill bit and put a lot of holes in it from both ends, then bash it with a long rod of some type like rebar. Then she falls out easily. I have done it both ways, just beating on it with the rebar and the drill method, believe me the drill will save you a lot of time. IF you have a O2 sensor behind the cat you will need a O2 similator. Have one of those, they work slick.

Somebody told me once you could pour ether down the TB while it's running and just burn the inside of the cat out. sounds like a dangerous venture to me. But if it works, i would assume that would be the easiest way. Don't even have to turn a wrench. just out of curiosity where would one get ether if they wanted to perform this technique?

you have to get an O2 simulator to replace the oxygen sensor. your engine is running too rich right now. i bet your gas mileage is worse right now too
