ok... my trucks got a 350 chevy in it... and it used to have thrush glasspacks on it. now i got some new glasspacks, but their a smaller diameter. do u think it will still be that loud? or louder? its true dual exhaust(dual glasspacks)
It'll be quieter! When ever you reduce the ID of the center tube the noise level goes down. Go to: Dynomax Mufflers and listen to the sound of every muffler they sell on your computer suond system.
