Yoshimura R-77D Street Stainless Slip-On Exhaust with Stainless Muffler | Suzuki GSX-R600 / GSX-R750 2011-2024

The Yoshimura R-77D Street Slip-On Exhaust is a bolt-on muffler for the 2011-2024 Suzuki GSX-R600 and GSX-R750, built with a stainless steel muffler sleeve and a carbon fiber cone end cap, and mounting directly to the stock header.

The R-77D is the dual-outlet development of Yoshimura's race-proven R-77. Where the standard R-77 exits through a single tail-pipe, the D version splits the outlet into a twin arrangement — a distinctly different look at the back of the bike, and the reason riders choose it over the standard canister rather than a difference in flow or fitment.

Underneath the styling it is the same trapezoidal R-77 architecture: the flat-sided sleeve packs far more sound-absorbing material around the core than a round canister of equivalent size, letting the baffle flow freely while keeping the exhaust usable on the road.

• Bolt-on slip-on muffler — retains the stock header and mid-pipe
• Dual-outlet R-77D tail-pipe arrangement
• Stainless steel muffler sleeve with carbon fiber cone end cap
• Trapezoidal R-77 profile for maximized internal packing volume
• Street Series — bolt-on installation with no ECU remapping required
• Yoshimura part number 960-1427 (manufacturer part 1160023520)
• Made in the USA by Yoshimura R&D of America

Fits the 2011-2024 Suzuki GSX-R600 and GSX-R750 as a direct bolt-on to the stock header, and is the choice for GSX-R riders wanting the R-77 note with the twin-outlet look. Check your local sound and emissions requirements before fitting.
