When assembling exhaust system do not  tighten clamps until components are aligned and clearances are checked.

1. Install under floor catalytic converter and the isolator supports to the underbody.
2. Position spherical gasket (2) with white side facing rear of vehicle, install springs, and bolts (3). Tighten bolts to 33 N.m (24 ft. lbs.).
3. Install I-Pipe/muffler assembly. See INSTALLATION .
4. Working from the front of system; align each component to maintain position and proper clearance with underbody parts.
5. Tighten band clamps to 55 N.m (40 ft. lbs.).
   CAUTION: Band clamps should never be tightened such that the two sides of the clamps are bottomed out against the center hourglass shaped center block. Once this occurs, the clamp band has been stretched and has lost its clamping force and must be replaced.
   NOTE: Maintain proper clamp orientation when replacing with new clamp.
6. Start the engine and inspect for exhaust leaks. Repair exhaust leaks as necessary.
7. Check the exhaust system for contact with the body panels. Make the necessary adjustments, if needed.
