I have seen many people say Suzuki=Yosh and that is why they chose that pipe. I think that attitude is ridiculous! You should buy a pipe for it's attributes, not for the name...sounds like marketing has a hold of you when you do that...anyway, I think the Yosh pipes and all race cores for that matter are way too loud for a dual sport bike like the S. My friend rides with a Yosh system on his XR650R and it is obnoxious and annoying. It reminds me of those LOUD exhausts on Hondas....Punk kid behind the wheel...or triple clamps in this case. Sorry but the more I can encourage people not to buy loud pipes the better. My advice is to buy the quietest one you can buy. BTW your DB to HP ratio is highest with a quiet pipe. When you're commuting that's what you'll appreciate most. Heck, why not just leave the exhaust alone??? It's quiet AND powerful!!! BUT we all must tinker RIGHT???
