GT40Marine Performance Rear Exhaust Kit

Sea-Doo RXP-X RXT-X 300 325 — Reduce Back-Pressure, Bolt-On Direct-Fit

Why Upgrade Your Exhaust Exit?

Your Sea-Doo leaves the factory with an exhaust system calibrated for emissions compliance, not maximum performance. The OEM rear exhaust exit creates measurable back-pressure that limits power output. The GT40Marine Performance Rear Exhaust Kit addresses this directly at the exhaust exit — the most accessible and highest-impact upgrade point in the system.

True Bolt-On — No Cutting, No Welding

Every component is machined to OEM dimensions for the Sea-Doo RXP-X and RXT-X 300/325 platform. Bolts directly onto existing mounts using all included hardware. Install time: under 3 hours for most owners.

Kit Includes

• Rear exhaust housing
• All necessary gaskets
• Stainless mounting hardware
• Step-by-step installation guide

2-Year Warranty + US-Based Support

Every exhaust kit ships with a 2-year GT40Marine warranty and access to our US-based Sea-Doo support team. All orders ship domestically from Bonney Lake, WA.
