Suzuki RM-Z450: Yoshimura RS-4 Exhaust
The 2011 Suzuki RM-Z450 is here, and the race proven Yoshimura RS-4 exhaust is now available for these awesome machines.
The RS-4 is the same exhaust that helped power Yoshimura racer Ryan Dungey (Rockstar Makita Suzuki) to the 2010 Supercross championship, so you know it delivers professional level performance.
The RS-4 is one of the most advanced pipes we’ve ever produced. Its duplex chamber design allows for a compact muffler that still has great flow and noise reduction. This means you’ll have a pipe that makes tons of usable power, with just enough of that satisfying Yoshimura sound to let everyone know you mean business.
There are a variety of inserts available, from the AMA Pro legal insert to the USFS approved insert, so the RS-4 can be matched to whatever conditions you might face.
Every RS-4 is made from lightweight materials to help you shed unnecessary weight from your machine, and come in a variety of finishes to suit your bike. The RS-4 exhaust is available as a stainless/aluminum slip-on with a carbon end-cap, or as a full system in stainless/aluminum, titanium/carbon, or full-carbon for those who want an even bigger performance boost.
As with all Yoshimura exhausts, each kit comes with easy to follow installation instructions and all of the necessary mounting hardware.
