I spoke with Yoshimura Japan who forwarded me to Yoshimura USA to order the R11 from Japan. Yoshi USA told me that the R11 slip ons are made in Japan, to order. I would have to put down a $400 deposit when I ordered and pay the balance when Yoshi USA get the R11 slip on and ships it to me. The R11 ranges in US Currency; $708 for the Stainless Steel to $834 for the Titanium. The R11 full exhaust starts at $1200 for the Stainless Can.



Where can I find any of these slip ons offered from Yoshi? The one that is available in the US, to me, is ugly. This slip on looks much better. It is on eBay but for $600-$800 vs. this one ( Yoshimura Alpha Signature Slip-On Exhaust Suzuki GSXS1000 / GSXS1000F - RevZilla ) this available for $400-$500.



Yoshimura product site : GSX-S1000/GSX-S1000F - SLIP-ON R-11 SINGLE EXIT : EEC APPROVED

If you already found it, why are you asking us? The Akrapovic and Yoshi R-11 slip-ons are ridiculously expensive for what they are. Might as well get the M4 GP slip-on for ~$250, they're all going to net you net to nothing power wise.

Yes, you are right. I did find the slip on selling on eBay in Japan, Australia, Germany, and the UK. Perhaps I should have been more specific and asked, "What Yoshi distributor in the USA can I purchase this slip on from?". I am aware of the Akra slip on being ridiculously expensive as well. I had the Akra slip on and mid pipe on my 15 R1 (big bucks). Those however, are easy enough to find. What I am looking for is the above mentioned slip on realistically priced for a Yoshi slip on. Perhaps that does not exist.

Thanks for recommending the m4. I have looked at it and it may be the best option, I don't care for keeping the stock chrome heat shield though. I have also ruled out any exhaust that to do come with a heat shield because the cat looks really ugly when exposed without the it.

I am not looking to get any more power out of this motorcycle. This bike is only to ride with my buddies on the street who don't ride on the track but have powerful bikes nonetheless.

In a perfect world all the slip-ons would be ~$300. I had a full Akrapovic system on my FZ-07 and it was under $700 shipped. I'm not planning on doing anything to the exhaust on this bike except maybe the cheap M4 GP slip-on. Everything else just isn't worth it. No point in doing a full system either for over 10% of the original cost of the bike, if it only nets you 8-15hp a rider lighter/and or more expeienced than you on a stock bike would still probably pull away.

No mid pipe for me. I am just getting this slip on for looks and sounds. My buddies with 1000cc's are not fast enough in the corners to pull away.

I know their expensive but the Yoshi's are so worth it. I had the system fitted. Then for good measure I fitted a bmc air filter, rapidbike Evo and quick shifter. I had dyno runs done pre and post mods and still have to tune the Evo but the results are simply awesome. I'm really glad I spent the money.

@Vamp; Those are good numbers, looks like a beast. Is that 80 nm or ft lbs? There is no denying that the R11 is the best looking exhaust for the GSX-S1000, especially the full exhaust. Those shiny pipes are not gonna be fun keeping clean though lol. I just have a hard time spending that much money on this bike. I have a 3/4 graves exhaust cat delete (headers are already beautiful blueing titanium) on my 2016 ZX10R and I paid $700 for. And it is Titanium and Carbon. Not stainless steel.

Ft-lb.

In nM it's 103 increased to 108 but it's fact the Rapid bike has filled in all the dips in the hp and torque curve's that's worth noting. With the quick shifter this thing just is just so quick. I've taken her to 145 and backed off, the bike was still pulling. It rides the way it should have from the factory. Still chasing more power and still have to tune the EVo, this was straight off the stock auto tune map after initial install.

Looking good. It should give up a few more just by getting a few more miles on the clock too. (Just guessing from the paint still on your front tyre;))
Can't wait to hear the final results:)
