Stainless Works Chevy Chevelle 1968-72 Performance Connect Chambered Exhaust - Manual

68-72 CHEVELLE CHAMBERED EXHAUST FOR FACTORY MANIFOLDS
INSTALLATION INSTRUCTIONS
Thanks for purchasing Stainless Works exhaust for your 68-72 Chevelle. 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 on the rear frame rails near the tailpipe exit.
1. Make sure vehicle is adequately supported on jackstands before crawling underneath.
Before assembling any s/s clamps, you want to make sure to apply never seize to the
threads to prevent galling. If never seize is not used the threads WILL gall and the clamp
will be scrap.
2. Assemble the front headpipes to the rear headpipes and install the assembly onto the
manifolds. Lightly snug the manifold studs but do not tighten.
3. Install the chambered mufflers onto the rear headpipes, hold in place with jackstands, and
snug clamps to hold in position. Install the tailpipes last. Working from the rear of the car
forward, align the tailpipes, then the chambered muffler assembly, and progressively work
from the rear of the car to the front. Some pipes may need to be trimmed to length for a
perfect fit.
4. After the exhaust system fits well, break the system apart and cut three small slots on each
pipe about ½” deep using a fine tooth hacksaw or an abrasive cut off wheel-only make
shallow cuts that will allow the pipe to compress and be sure not to make them deeper than
the overlap in the joint. Deburr each joint, 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 using a ¼” drive ratchet, and make sure to apply never seize to all clamp
threads. Do not overtighten 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.
