Description
Ensure leak-free sealing on your Yamaha SuperJet with R&D Pipe when using an aftermarket exhaust pipe with the R&D Pipe Replacement O-Ring Kit. This set of high-quality, heat-resistant O-rings provides reliable sealing at the head/pipe junction, preventing exhaust leaks that rob power and cause overheating.
Why Replace O-Rings
- Premium material resists high exhaust temps and compression set
- Restores proper seal after repeated heat cycles
- Prevents power-robbing exhaust leaks
- Set of 3 – complete for SuperJet R&D pipe installs
Old or hardened O-rings are a common source of exhaust leaks on SuperJets. Fresh R&D O-rings ensure tight fitment, maximum power transfer, and cleaner running – essential whenever installing or servicing an aftermarket pipe.
Durability Focused
R&D selects compounds designed for marine exhaust environments: fuel, oil, heat, and vibration resistant.
- Improves backpressure consistency for better tuning
- Easy swap during pipe removal
- Low-cost insurance against performance loss
- Recommended for every pipe reinstall
Keep your SuperJet exhaust tight and efficient.
Install Tip
Clean flange surfaces, lubricate O-rings lightly with exhaust sealant or anti-seize, torque pipe bolts evenly. Check for leaks after first heat cycle.
