Yamaha R1 (2004-06) Slip-On Exhaust Systems: Our exclusive V.A.L.E.TM mounting system eliminates the need for springs resulting a more secure mounting. Huge horsepower gain of 6.7hp @ 7500rpm (right where you can use the extra power) and a peak horsepower of 4.1hp @ 11,500rpm. Total peak horsepower leapt from 152.7hp to 156.8hp simply by installing the Twobros M2 slip-on exhaust system!

Our small oval M-2 V.A.L.E.™ exhaust system features our exclusive Teflon coated, blunted, cast magnesium outlet that not only looks great but also allows for various silencer inserts.

The V.A.L.E. TM inlet design eliminates the use of springs and creates an adjustable mount that is solid when fixed in place. The system also features a thinwall s-bend tube that connects to the factory header pipes.
