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!

Not as loud . Had to do some modification to rack support. No big deal. Also moved engine to left for 3stage header to clear frame (Ct200u). Thanks

have this on a mild 212 predator that had a open header, took some of the harshness out and gave it a nice throaty tone. They are a little pricey but I'd say they are worth it. I can cruise round after dark now and not have lights pop on as I go by lol
