exhaust question
#21
Removing a cat is a Federal offense in the US regardless if you have emissions or not and the fines aren't cheap. You will gain hardly anything by removing it, especially on a 3.9 and you can make your exhaust plenty obnoxious while keeping the cat. Straight pipes sound awful on most engines, inlcuding V8s, do everyone a favor and get a good muffler. Any tool can make an exhaust loud, making it sound GOOD is another story.

I think exaust going through the hood sound kicks *** especially on V8s, but thats illegal and would bring down the back pressure, but do they have smaller catilac converters, becuase ifs illegal to take them off i need smaller ones because once i do the swap, im going to have each side be on an indevidual pipe that exits between the cab and rear wheels on each side

Backpressure is not a good thing. Ask anybody who has ever built a race motor and see how much backpressure they try to get out of the exhaust.... none. The best possible senario is to tune the headers so there is a vacuum at the collector to bring backpressure down to 0 and literally suck the exhaust out of the cylinders.
