Monza exhaust system comes with two separate sections of exhaust pipe, a muffler, and tow chrome plated tips. The arrow represents where the two sections of pipe connect. There should also be five exhaust pipe clamps. Three of the clamps are 2.5" and they are used on the exhaust pipe connections. The other two clamps are 2.25" and are used to hold the tips to the muffler.

This picture compares the two systems. The exhaust pipe is almost exactly the same except that it is 2.5" in diameter while the stock pipe is 2.25" in diameter. Also note that the Monza system is slightly heavier than it's stock counterpart.

Installation procedure

1. Remove the old components.
2. Jack up the car on ramps or jack stands. Do not use the stock jack, as they often fail.
3. Remove the factory muffler using a 15mm wrench and by taking the rubber hangers off their mounts. A large hammer can be used to get it off of the factory exhaust pipe.
4. Remove the 15mm connection at the catalytic converter.
5. Remove the other hanger halfway back on the long exhaust pipe and pull it out from under the car. Watch you're eyes for falling rust.
6. Assemble everything under the car but do not tighten anything down yet. Be sure all the clamps point down to make it easier to tighten. This picture represents the trickiest part of installation. It is the area over top the left rear axle. The pipe comes very close to the spare tire wheel well. Be sure to get it as far away as possible by twisting the various pipe connections.

   

7. Once everything is bolted up and seems right, tighten the clamps but don't go too tight. Don't worry about exhaust leaks at this point. Get out from under the car and start it.
8. Drive it around gently for a little bit to listen for rattles. In this case the only rattle heard was pipe which connects to the catalytic converter. By loosening the connection between the two sections of Monza pipe, the entire assembly was able to move downwards to allow more clearance between the floor pan and the catalytic converter..
9. After the pipe is straightened out and everything is rattle free, the muffler may require straightening out. It sat too high and too far in on the right side so a pipe wrench was used to tweak the muffler hanger. It used to stick straight out.

   

10. Align thips and tighten their connections down.
11. Go back out for another test drive and make sure nothing rattles or squeaks. If it's hitting you may have to loosen/tweak/tighten some of the connections or bend some of the hangers.

Notes

• It will stink at first because the paint is burning off the pipe up near the cat. This will last for 100 miles or so.
• After a few hundred miles, tighten all the clamps down again.
• If the exhaust system continues to rattle and shake, a trip to the local muffler shop may be required. On average, they should be able to make any welds and adjustments necessary for around $ 50.
