straight pipes on an NA 55 motor
Catalytic converters would continue to be used in order to keep with State emessions. In the past I have heard a 350 with no muffler/resonator but it wasnt at all loud, kinda raspy as a matter of fact. In no means am I comparing a V8 to a 6 but I was suprised at the lack of volume.
Would all back pressure be elimintated taking out the muffler? Would it generate a drone at high way speeds?
what are your thoughts...
