The guy down the road from me started to do exhausts and I thought to myself wonder if he can do it for cheap. I already have the 2 pipes from my bumper up to my cab so all I need is pipe from my header to the end of the cab. My question is can I just get away with ditching my cat and just keeping my one o2 sensor on the one side? Will it throw off the computer at all? I think it will be bad ***. My buddy got his jeep exhaust done there and from the cat back he hung it and bent it for 60.00. Im just not sure if it will sound good I think it will cause it will be all straight pipe.

 

right now, I have my truck dumped after the cat..It sounds like a open exhaust. Sounds good, but is abrasive. Pipe it out the back...might help. Id be interested to see how it sounds, but Id keep something in there.
As for the comp, you could get a reistor and fool the comp, or just try unplugging it now, and see.

 

Right now I have the cat then about a foot of pipe after the cat and its not too loud in my truck sounds pretty good but I think it could be better. I know last time I had my o2 sensor out my truck ran like complete horrible crap!
