When I had it put on the dude asked me how loud I wanted it, I said not very....well the system he put on had, I believe, 18" glass-pacs on it...My question, can I take it, have regular mufflers installed to replace the glass-pacs, what kind of sound would that give me....I want the two pipes out the back but I don't really want the noise. The noise would be fine if I was like 16 but I am 10 years older than that..Any info??? Would have-n regulat mufflers installed be the less costly fix?
