i just bought my first bike 3 months ago(01 zx7) and im loving it. besides from me lowering it one inch she is bone stock.Im ready for a bolt on exhaust and i came across blue flame u.s.a. I dont know anyone using them on ther bikes so i was wondering if anyone here has had any good/bad experiences with this company.I know that muzzy and yosh. are supposed to be great but i wanna do something different than the normal. thank for your time.
