WORX Racing Exhaust Sleeve for Yamaha SuperJet (1991-2020) - WR04041
The WORX Racing exhaust sleeve is a billet aluminum insert for the OEM exhaust muffler on 1991-2020 Yamaha SuperJet models. It fits 1991-2020 Yamaha SuperJet (2-stroke, including the 701) and helps correct a stock exhaust outlet that can leave top-end pull and backpressure on the table. This sleeve slides into the OEM exhaust stinger with no drilling or permanent modification, making it a simple exhaust mod for riders dialing in a two-stroke SuperJet setup. It is built for riders looking for a cleaner top-end feel and improved exhaust response from the stock muffler layout. Installation is straightforward, but rejetting may be required depending on carburetor settings and the rest of your engine package. Does not fit the 2021+ four-stroke SuperJet.
➕ Performance Benefits 🔽
- Improved backpressure: Reduces stinger diameter to help the exhaust system maintain stronger pressure at higher rpm.
- Better top-end pull: Helps the 2-stroke SuperJet carry speed more cleanly when the stock muffler outlet is too open for your setup.
- Simple install: Slides into the OEM exhaust stinger with no drilling or permanent modification to the stock exhaust system.
