It sounds amazing and boosts torque, mileage, and throttle response. Part Number: FLO - 705. Features: 4 - inch turbo - back exhaust, with muffler, aluminized steel, dual side exit, easy install mounting to OE hangers.

How to use: Install the exhaust system following the included instructions. It's designed to mount to your vehicle's OE hangers, so it should be a straightforward process. Make sure all clamps are tightened properly. Notice: Since this product has been discontinued, replacement parts might be hard to find. Be gentle during installation to avoid damaging the aluminized steel. Maintenance: Periodically check the clamps to ensure they're still tight. You can clean the exhaust with a mild soap and water solution to keep it looking good. If you notice any unusual noises or performance issues, have it checked out by a professional.
