twice in one week i have been pulled over for my exhaust and been given a ticket. apparently it is too loud. I have a built y8 @15psi 250-300hp and 2.5" back to a knock-off N1 muffler. high-flow cat (resonator). What can I do? I don't want to pay too much for a cat-back, but a muffler that I can weld in that will quiet me down would be good. Suggestions? Do the silencers for these mufflers really work?
