Yoshimura - RS-4 Signature Series Full System (Suzuki)

Built straight from Yoshimura’s racing pedigree, the RS-4 Signature Series Full System gives Suzuki riders that factory-level performance, sound, and style. Designed to pull harder out of the gate and add torque throughout the rev range, the RS-4 helps your RM-Z450 launch strong, hook up clean, and pull longer down the straight. It’s a complete system engineered to win — lighter than stock, smoother through the midrange, and tuned for that deep Yoshimura growl that makes a four-stroke sound just right.

The RS-4’s pentagonal canister isn’t just for looks — it houses Yoshimura’s Polyresonant Duplex Chamber and stepped baffle design to control noise while boosting power. A stainless steel header and carbon fiber end cap give it a clean factory finish that can take real abuse. And if you want to cut even more weight, Yoshimura offers titanium versions that look as good as they perform.

Why We Like It:
You can feel the race DNA in this system. Throttle response snaps to life, the midrange torque feels meatier, and it still keeps sound levels smart and clean. The RS-4 gives your Suzuki that pro-level punch without making it harsh or high-maintenance — just smooth, reliable power that hits right when you need it.

Why It’ll Work for You:
This system transforms how your bike builds power — smoother off the bottom, stronger through the mid, and more drive when you twist it wide open. The Polyresonant Chamber controls sound without killing flow, while the stepped baffle helps your RM-Z pull harder through every gear. It’s a true race-bred setup that delivers consistent performance, lighter weight, and that unmistakable Yoshimura tone — refined, powerful, and ready for the gate.

 

Key Features:

  • Pentagonal-shaped muffler sleeve for unique factory styling

  • Front muffler cap functions as a Polyresonant Duplex Chamber to reduce noise

Works great. Wish pieces came apart.
Size: 15-Foot
My only suggestion is that the pieces are made more easily to take apart so that you can buy two and combine them for a longer ramp. But they don’t advertise that capability so i cant dock a star for it. Otherwise work great.

Nice and easy does it
Size: 15-Foot
Perfect for when you're camping with full hookups. This keeps your sewer hose off the ground and up just enough to drain while camping. It spreads easy and evenly. I like not having to put blocks, metal hooks, or something else to set the hose on. This is quick and easy. It's very durable plastic and if needed easy to rinse off. It comes with an orange piece that hooks onto it to keep it together to make it great for storing. We have a gray tank in front and gray and black in back. We use two sewer hoses when camping with full hookup. I bought two of these so one is under each sewer hose. The look of these is just "neater" versus tacky like my uneven blocks were. They are very stable once put in place whether on concrete or gravel campsite.

Perfect, Safe Hose for My Rain Barrel Setup
Style: 1/2-Inch ID, Size: 4 Feet
This Camco TastePURE 4-foot water hose has been perfect for my rain barrel setup. The length is exactly what I needed for a clean, simple connection without excess hose to deal with. I really appreciate that it’s drinking-water safe with no lead, BPA, or phthalates. Even though I’m using it with a rain barrel, it’s reassuring to know it’s made from safe materials. The reinforced design feels sturdy and durable, not flimsy like cheaper hoses. The 1/2” inside diameter provides solid water flow, and it’s made in the USA, which is a nice bonus. Great quality, reliable, and exactly what I was looking for. Easy 5 stars.

Wow, It’s 2026, I purchased in 2022!
Style: 5/8-Inch ID, Size: 50-Foot
I just looked up this hose again in my order history to get another. I was shocked to see that I ordered it four years ago. It held up through the most brutal northeast winter in decades, fully expected to it have burst, but no! Reliable and recommended!
