1997-04 C5 Chevrolet Corvette Axle Back Exhaust - EX1002

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.Place each NXT STEP PERFORMANCE over axle and elbow pipe assembly into position with clamps (DO NOT tighten the clamps) then bolt onto the flange using the provided gaskets.

2. Place a clamp on the expanded end of the NXT STEP PERFORMANCE mufflers.

3. On automatic transmission equipped models, slide rubber muffler hangers on to the muffler brackets, now place the mufflers into position attaching them to the over axle/elbow pipe assemblies and bolt the rubber hangers back into position using the original bolts tightening them to 12-15 ft. lbs. of torque. On manual transmission equipped models you should be able to slide muffler hangers back into their rubber brackets and attach mufflers to over axle pipe assembly, DO NOT tighten the clamps.

4. Holding exhaust tips into proper position, tighten the clamps to 32-35 ft. lbs. and the flanges to 35-40 ft. lbs.

5. Check your exhaust system for proper clearance under the vehicle and also for tip alignment.

6. Horizontal adjustments can be made by loosening the flange connecting the over axle pipes to the exhaust. Vertical adjustments can be made by loosening the clamp securing the mufflers to the over axle and elbow pipe.

7. Once position has been determined to be correct, swing the anti-sway bar back into position reinstalling the original hardware previously removed. Torque the upper bolts to 45-49 ft. lbs. and the lower nuts to 65-70 ft. lbs.

8. Before starting your vehicle, make sure to check all wires, hoses, brake lines, body parts and tires for safe clearance from the exhaust system.

9. 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).
