The RS-4 is a technological marvel. It features a Yoshimura duplex chamber which cancels out negative exhaust pulses; & effectively acts as a mechanical baffle before the actual perforated baffle area. This in turn improves power while lowering dB. This Full System comes with a stainless steel header and mid-pipe, aluminum muffler sleeve, installation hardware, and detailed instructions to get you moving! An AMA-approved sound insert comes installed in the muffler, along with a 2 meter-Max insert in the box.

Bark and Bite!
I installed this full system on a 2019 CRF450L. A slip-on muffler will not fit onto the stock pipe. When coupled with a programmable ECU my bike now both barks as well as bites. Very deep, throaty note coming from the muffler. Much better performance and sound than stock exhaust system. Highly recommend!

CRF450L
What a great sounding pipe. This fit onto my 2019 CRF450L perfectly and comes with spark arrestor insert. Im using the Vortex ecu and it really wakes up the bike.

Exhaust with Mojo
This system is light and sounds great! I combined it with an aftermarket Vortex CPU and I love it.

Buy it you won't be disappointed
Installed with the Vortex ECU. The combination of the Yoshimura header and Vortex ECU makes a big difference in bike rideability.. Well worth the cost.
