Toce Performance Yamaha R1 (2009-2014) T-Slash Exhaust System
The Yamaha R1 T-Slash Exhaust System quickly became the patriarch of the Toce Line when they were released 8 years ago. Not only designed to follow the contour of the Yamaha R1's tail section. The exhaust has been 3rd party dyno proven to make more power with our light weight mandrel bent stainless steel Y-Pipe than competitors. All the while providing the lowest note possible, its not a wonder why we have shipped these systems daily across the world since their release.

I’m very happy thanks
I love it best sounding exhaust I’ve ever heard
Everyone that has seen it and heard it say the same
Beautiful product. Great sound and good fitment.
I am very happy for this product! Amaizing sound! Best deal!
Product is great. The sound is excellent loud and deep people will for sure hear you coming . Assembly was not to difficult. Only complaint the directions were not descriptive at all.
The best exhaust on the market, looks great and ......, so loud just love it !!!
These things sound great! Would have been 5 stars if one of the slip ons hadn’t had stripped threading. Haven’t had an opportunity to ride it though
Really simple installation. Fit and finish was absolutely perfect. Haven’t heard a better sounding exhaust. Really loud. Videos don’t do it justice. Couldn’t be happier about this exhaust
Very well made, as a welder myself I can appreciate the effort that goes into this. Sounds amazing looks amazing. 10/10
Best sounding exhaust I have heard on any R1! I had no issues with the install and was done in about 2 hours. The kit came complete with everything needed and fit perfectly. Video clips don't do justice how mean these pipes make your R1. Night and day difference compared to the stock pipes. People will actually know you're coming. Opens up the R1 how it should be. Excellent product!
I didn't think the Toce was going to be this loud! Your neighbors are definitely going to hate you. Oh and when you get off the gas! Pop pop pop pop pop. It looks so good, I'm getting nothing but compliments.
UNREAL! My bike sounds down right pissed off now! Aesthetically, it looks perfect. Obviously I don't have a dyno, but I'm certain I gained some ponies. My bike comes up noticeably easier. Anyways, it honestly sounds like a Lamborghini now! I couldn't be more pleased and my girl is turning five times as many heads than before. Marks is sooooo helpful; a real pleasure to deal with. THANK YOU TOCE PERFORMANCE FOR GIVING ME THE BIKE I WANT!
