2011-14 Ford Mustang GT/Boss 302 5.0 Axle Back Race Exhaust - EX3036R

Use mild car/motorcycle soap to clean the exhaust system—do not use any abrasives or degreasers. Clean your exhaust with metal/stainless polish every 1-2 months to retain the luster and remove dirt and grime. Avoid contaminating exhaust surfaces when hot.

Warning: Use extreme caution during installation. Torque all fasteners according to manufacturer’s torque values and tightening sequence. DO NOT use air impact tools to tighten fasteners on NXT STEP PERFORMANCE exhaust systems. Use of such tools may result in bent flanges or gasket contact areas leading to exhaust leaks.

1. Insert the expanded end of the (driver-side) L/H muffler assembly into OE ball clamp and install the hangers into the rubber isolators.
2. Repeat step 2 for the installation of the (passenger-side) R/H muffler assembly.
3. Check your exhaust system for proper clearance under the vehicle and also for tip alignment. If tips do not protrude evenly, loosen the factory band clamp at the X-pipe to over-axle pipe on the affected side, and slide over-axle pipe until tips protrude evenly. There is plenty of adjustment under the band clamp.
4. Once position has been determined to be correct, tighten the clamps to 32-35 ft. lbs.
5. Before starting your vehicle, make sure to check all wires, hoses, brake lines, body parts and tires for safe clearance from the exhaust system.
6. Start vehicle and check for any leaks. If any leaks are found, determine cause (such as loose or incorrectly positioned clamp) and repair as necessary (When you first start your vehicle after the installation of your new NXT STEP PERFORMANCE exhaust system, there may be some smoke and fumes coming from the system. This is a protective oil based coating used in the manufacturing of mandrel bent performance exhaust tubing. This is not a problem and will disappear within a very short period of time after the exhaust has reached normal operating temperatures).
