Upgrade your Suzuki LT-R450 with the Yoshimura RS-5 full exhaust system. Learn about performance gains, sound, and fitment for off-road riding.
Quick answer
The Yoshimura RS-5 full exhaust system is a top choice for Suzuki LT-R450 owners seeking a durable, high-performance upgrade with a deep, aggressive sound and significant power gains.
Why the RS-5 Stands Out for the LT-R450
The RS-5 is designed specifically for the Suzuki LT-R450, ensuring a precise fit and optimized performance. Its four-sided trapezoidal muffler isn't just for looks—it creates a deep, pleasing sound that sets it apart from round or oval cans. The high-flow, straight-through baffle maximizes exhaust flow, which translates to noticeable power gains across the rev range, especially when paired with other intake and tuning mods.
Construction and Durability
Built with stainless steel internals and a stainless steel full exhaust system, the RS-5 is designed to withstand the harsh conditions of off-road riding. The aluminum muffler shell keeps weight down without sacrificing strength. This combination means you get a pipe that resists corrosion and holds up to mud, water, and trail impacts better than many painted or plated alternatives.
Sound and Compliance
The RS-5 produces a deep, throaty note that many riders prefer for trail and desert riding. However, it is louder than stock, so check local noise ordinances if you ride on public land or in organized events with sound limits. The trapezoidal shape also helps direct sound away from the rider, making long days in the saddle more comfortable.
How to decide if the RS-5 is right for your LT-R450
- Performance goal: If you want maximum power from your LT-R450 and plan to re-jet or tune the ECU, the RS-5's straight-through design delivers measurable gains. If you only want a sound upgrade without tuning, a slip-on may be simpler.
- Riding environment: The RS-5 is louder than stock. It's ideal for open desert, dunes, or private tracks where noise isn't restricted. For quiet forest trails or sound-checked events, consider a spark-arrested enduro system instead. Check local noise limits before buying.
- Budget and value: At a catalog comparison price of $819 (currently $491.40), the RS-5 full system offers significant savings over many competitors. It's a strong value for a full stainless system with a premium muffler.
- Fitment and installation: This system fits 2006-2010 Suzuki LT-R450 models. Installation requires basic mechanical skills and tools. No major modifications are needed, but you should check for clearance with aftermarket skid plates or chassis guards. Verify your model year and existing accessories before ordering.
