Installing glasspack

Any fledgling mechanic can install a set in a few hours to replace his stock mufflers. Cut the exhaust pipe just in front of and just behind your stock mufflers by wrapping the pipe cutter around the pipe and slowly turning it. The cutter scores the pipe little by little until it cuts all the way through the pipe, ensuring a clean, smooth cut.

Slide the Glass Pack into place, removing extra exhaust pipe if necessary with the pipe cutter. Secure the muffler on both the inlet and outlet sides by installing the exhaust clamps around the lip of the muffler and exhaust pipe. Tighten the clamps with a crescent wrench until the muffler will no longer move freely when pulled on. Secure the newly installed Glass Pack by attaching muffler hangers to the solid areas on your car's frame, wrapping muffler straps around the muffler itself and tightening with a screwdriver.

Make sure the exhaust system does not rub on the undercarriage of the car and is securely fastened to the frame. Step 1 Drive your car up onto the jacks or grease pit and set the parking brake. If more space is needed, it will be necessary to cut the exhaust tubing on one or both ends to accommodate the new unit. Cut carefully; if too much tubing is removed, the muffler will not install correctly. Take out only as much as you need, whether you are welding the new unit in or clamping it on.

Install the glasspack. If you are welding the new muffler in, be sure to get a percent bead all the way around each end so there are no exhaust leaks in the system. Place the muffler carefully between the front and rear tubing and tack it so that it is suspended and check your tolerances. Once the muffler is correctly in place, complete the full weld. Always wear welding safety equipment and make sure the vehicle is sitting on jack stands if it is necessary to elevate it.

If you are clamping the muffler on, always use new units. They can be found cheaply at any auto supply store and will last several times longer than the old clamps. Similar to the welding method, the muffler will be placed between the front and rear tubing, but simply clamped into place. Get the clamps as tight as you can to avoid failure or exhaust leaks.
