I rode mine for like a year with stock pipes and then I got T-5s. Wow what a difference. I goty mine ported a year and a half ago, and wow what a difference. again, Wish I had done at least the pipes the day I bought it. Just get pipes and porting now, you won't regret it. If you really want a sleeper, like I said, the PT pipes in black could be mistaken for stock, maybe do a 4mil with the stock head cut., but you're gonna be over budget. But just do yourself a favor and get at least pipes and porting now, you won't regret it.
