Product Description
Classic RLV #4104 stock class muffler with a 1 5/16" opening. Dyno tuned to actually create better performance on most engines. Mandated by most karting sanctions. Comes with clamp. 7" long
Don't let the name "Silencer" / "Muffler" fool you, it is designed to help give the engine a little extra torque, it does in fact take the edge of the POP POP during deceleration, but it's still LOUD.
The B91XL muffler fits the following pipes:
- KD5438
- GPS-0010
- GPS-0020
- KD5432
- KD5435
If using a muffler with header pipe, it must be supported with a brace to prevent damage to the pipe. we would recommend part #KDHBS.

It fit the header on my predator 420 nice and snug and the clamp tightened down securely . I also safety wired it as suggested. The stock mode rated silencer seems to compliment the stage one upgrades on my engine, still allowing it to run to its full potential while keeping excess noise to a minimum. I am happy with the purchase.
