70-81 CAMARO HOT ROD EXHAUST
INSTALLATION INSTRUCTIONS
Thanks for purchasing a Stainless Works exhaust for your 70-81 Camaro. Please follow these steps to
ensure that your installation goes as planned. We recommend purchasing high temp RTV sealant to use
on all pipe joints, and you will need to fabricate or purchase hangers for the system- normally hang the
exhaust system using two hangers under the rear seat and two factory rubber biscuits on the rear frame
rails near the tailpipe exit.
1. Make sure vehicle is adequately supported on jackstands before crawling underneath. Starting at
the rear of the vehicle, with the axle at full droop, fish the tailpipe into the factory hanger bracket
and hold in place using jackstands. The tailpipe exits are left long to allow for trimming to length
on the car for a perfect fit. We recommend trimming the tailpipe exits last so that you can have
the rest of the exhaust mounted for a perfect fit. Insert overaxle pipes into place and secure to
tailpipe using a clamp.
2. Install a clamp onto each muffler outlet and slip the mufflers onto the overaxle pipe-the mufflers
are sized so that they can only be installed one way. The mufflers will fit into a pocket under the
rear seat. Snug clamp to hold in place.
3. With both mufflers in place, install 2 clamps over muffler inlets and install the lead pipes. Next,
bolt the collector adapters to header collectors, and measure the length which needs to be cut off
the headpipes-make sure to measure twice and cut once! Cut with a fine blade hacksaw or a chop
saw with an abrasive blade. Deburr pipe after cutting and remove collector adapter. Slip all pipes
into place for trial fit, and then mount exhaust using the hangers you have made or purchased.
Trim the tailpipe outlets to length. Note that some systems also include an X-pipe that goes
between the muffler inlets and the lead pipes
4. After the exhaust system fits well, break the system apart and coat each joint with high temp RTV.
The high temp RTV makes disassembling the exhaust system much easier, and also improves the
integrity of the seal.
5. Tighten all clamps. You want the clamps snug enough to prevent the pipes from turning. Make
sure to have at least ½” of clearance between the exhaust system and any other components. If the
vehicle is going to be used for competition use, we recommend putting a small tack weld at each
joint for added security.
6. Drive car at legal speeds for 10-20 miles and re-tighten all clamps.
