Samson Silver Bullet Slip on muffler for FLT Dresser models 95/L.

Power Chamber.

"SILVER BULLET" SLIP ON MUFFLERS FOR FLT DRESSER MODELS 1995/LATER - Samson

If you are looking to improve your power output and enhance your exhaust's sound, then a pair of these slip-on mufflers from Samson is a logical choice. To create the correct back pressure for the engine while maintaining a high exhaust flow rate, these mufflers feature an all steel, welded in power chamber/baffle system. This power chamber (shown below) collects the exhaust gases and then funnels them into the spiral louvered baffle. Unlike baffles with replaceable packing, the power chamber will never require replacement and will maintain the same exhaust note for years to come. The Silver Bullet mufflers have a tapered tail end and measure 29" in length, are 3" O.D. and include rear mounting hardware. Sold in pairs. Fits all Dresser models including FLHR 1995/Later.

Part#: MU97091 - Silver Bullet. Tapered. ... $413.95 including FREE SHIPPING*



Parts necessary to complete installation:
Use muffler to exhaust pipe clamps MU98011: High quality clamps made of 1/8" thick cold rolled steel 3/4" wide. Use with brackets to fasten exhaust pipes securely to frame or to secure mufflers to exhaust pipes.
Part #MU98011 - 1 7/8" I.D. ... $4.40 (must be purchased with pipes)
