Exhaust

91 silverado 350tbi

How would a dual exhaust coming off the cat with 3" pipe and 3 1/2" tips sound? Possibly 45 degree them out behind the wheels

I am looking for loud but not snap crackle pop, and I want to keep the cat on cause to big of fine to get caught w/ out one.

the cat is probably going to take away both the crackle and some volume of the exaust, i would go with flowmasters with turndowns as close to the back of the cab as possible, that way you can still get a little more volume, also the sound will rebound off of the asphalt and the bed of the truck, should give you a good deep rumble

no turndowns for me.................I want my cat as well................

well what kind of sound are you lookin for, are you goin to put any other muffler on?

2.5 pipes with a good muffler soud OK... some of the people run only the converter and no muffler (too loud). I run a large magnaflow muffler (two in , two out) configuration then duals out each side.... behind rear tire...or many run the pipes out under the bumper. No way would I run turn-downs under the body of any vehicle...."just my view".
