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.
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

At first, I just had the header pipe and it was too loud for my neighborhood setting. Whenever I got the muffler, it eliminates the popping noise when you decelerate and it makes it a good bit quieter. Also the shipping was amazing. Was supposed to come on a Monday and came on Saturday around noon. Thank you GoPowersports!
