That's exactly what I want to.I had Yoshimura race-only on my old '93 Gixxer 6. It was pretty loud! Not sure what the current Yosh sounds like compared to that one. Oddly enough I'm looking for an exhaust that sounds nice but is NOT too loud (but louder than stock!).
The only problem with your stock exhaust is the weight. I know when i changed mine, i couldnt believe how heavy the stock muffler was compared to the aftermarket.Well basically the stock muffler is setup like a race pipe inside now. I had a local exhuast shop do some work on it. Then I painted it black with high heat paint.
+2 on the Leo!I have a Leo Vince on my 04 and Like like the fact that under 6k it's for the most part tame however once I'm over 8k it wakes up and over 10k it's just stupid loud
