Ever seen a Chevrolet 15 Passenger express van with duel exhaust? We just put duels on ours. 16in glasspacks and 3inch exhaust pipe. She really roars with that 454 pulling a 28 Foot trailer with my race car in it going down the highway.
I'll bet that does sound nice! How did you route your left side exhaust? I am hoping to put true duals on my '98 with a 5.7. did you put a "H" pipe on it?
