Stainless Works Chevy Camaro 1969 Exhaust: Small Block Factory Reproduction - Manual

67-68, 69 CAMARO, 68-72 NOVA CHAMBERED EXHAUST FOR FACTORY
MANIFOLDS INSTALLATION INSTRUCTIONS
Thanks for purchasing Stainless Works exhaust for your Camaro or Nova. 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. On 67-68
Camaros and 68-72 Novas, 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. 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 headpipes to the intermediate pipes and install the assembly onto the manifolds.
Lightly snug the manifold studs but do not tighten.
3. Install the overaxle pipes onto the intermediate pipes. Next, assemble the chambered muffler
bodies together by inserting cap screws (not supplied) through the muffler brackets. Install the
body assembly onto the overaxle pipes, 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.
