Key Product Features

The Big Gun 07-7702 ECO Slip-On is built to handle the heat and vibration common in side-by-side use.

• Construction: Uses 0.049 stainless steel tubing and a 6061 brushed aluminum muffler canister.

• Durability: Features a slip-fit mid-pipe design that allows sub-frame movement, helping prevent the muffler brackets from cracking during aggressive riding.

• Sound & Safety: Rated at approximately 96–98dB (track and trail legal) and includes a removable USFS-approved spark arrestor.

• Internal Design: Features a wrapped perforated core for a deep, throaty exhaust note.

Performance & Tuning

While this is a slip-on system, the RZR 800 is fuel-injected. Under most conditions, the stock ECU can compensate for the increased airflow. However, for maximum power gains and to ensure the engine doesn't run too lean (which causes excess heat), many riders pair this with a Power Tork Fuel Controller
