Description
The R-77D is a dual-outlet version of the race-proven R-77.
The R-77D boasts a carbon fiber cone end-cap and polished stainless steel dual outlet turndown.
The R-77D requires no inserts or restricters, increasing muffler packing life, and provides 5% more open exhaust outlet area and as much as 3 decibels lower sound output (compared to open standard R-77.)
The R-77D also offers greater gains in bottom and mid-range power without restrictive inserts.
This Slip-On System includes R-77D muffler, stainless steel mid-pipe, installation hardware, and step-by-step instructions.
