I do have 2 Harley's an both have straight drag pipes, i have a 02 duramax truck with 5" straight pipe an 7" tip, around here everything is loud, but its small towns an mostly all rural, but i do respect the people's opinion that would chose to live in a quiet area, but thats just not for me. Also i own 7 2stroke's all have various brands of aftermarket exhausts an all 7 running together isnt as loud as one built an piped 4stroke, i built a high compression cammed 440ex for a friend last year an its got a full yoshimira exhaust an it makes your ears ring after running it
