- Fuel tuning is absolutely required when installing this exhaust, failure to do so will void the warranty of the exhaust and possibly your machine.
- This system will use a wideband oxygen sensor that has 18MM threads and we absolutely recommend using the HMF AFR+ Gen4 Fuel Controller.
- Gun Metal and Blackout finish takes up to an additional 4 business weeks to ship.
