Installation of CORSA Exhaust System:
NOTE: Apply the anti-seize lubricant (supplied) to the threads ONLY of all the clamps and flange bolts. Failure to follow this
procedure can cause nuts to seize on clamps and potentially destroy threads. After applying anti-seize lubricant, be sure to
thoroughly clean your hands, as lubricant will tarnish stainless steel. All clamps should be tightened using a properly calibrated
Torque Wrench. Using an air impact gun will damage the clamp and reduce its ability to
effectively seal the joint. It may also cause the joint to separate, thereby causing damage
to your exhaust system and to your vehicle.
NOTE: Align all clamps so that the center of the clamp bolt is 90 degrees from the notch in
the pipe. (See Fig. CLAMP)
1. Remove all exhaust system components from the shipping boxes, including clamps and
hardware
2. Locate the Corsa head pipe assembly. Insert the hanger into the factory rubber grommet. (Fig G) Next, align the head pipe
flange with the stock flange, and secure with the two nuts set aside in step one of the removal process using the ratchet and
15mm socket. (Fig H).
For 128.3” wheel base trucks, skip to Step #4. For 140.5” wheel base trucks, continue to Step #3.
3. Locate the 140.5” WB adapter pipe and a 3.0” clamp. Slide the clamp over the expanded inlet of the pipe and then slide the
adapter onto the outlet end of the head pipe. Orient the clamp such that the bolt is on the driver’s side of the pipe with the nut
towards the ground. Snugly tighten the clamp using the ratchet and 15mm socket. (Fig I).
4. Locate the muffler and another 3.0” clamp. Slide the clamp over the expanded inlet of the muffler and then slide the muffler
onto either the end of the head pipe (128.3” WB trucks) or the end of the 140.5WB adapter pipe (140.5 WB trucks). Make
sure the drain hole in muffler is oriented downwards. Snugly tighten the clamp using the ratchet and 15mm socket. (Fig J)
5. Locate the tail pipe and another 3.0” clamp. Slide the clamp over the expansion and from the rear of the vehicle, feed the pipe
over the rear axle. Insert the hangers into the rubber grommets both near the muffler and the single hanger near the end of
the tail pipe, then slide the tailpipe onto the end of the muffler. Adjust the tail pipe such that the portion of the hangers inside
the grommets are level and parallel to the ground. Snugly tighten the clamp using the ratchet and 15mm socket. (Fig K, L, M, &
N)
6. Locate another 3.0” clamp and the tip assembly. Slide the clamp over the expansion and then slide the tip assembly onto the
tail pipe. Adjust rotation of tip assembly to align the tips with the side of the truck bed. Snugly tighten the clamp using the
ratchet and 15mm socket. (Fig O & P)
7. Ensure the exhaust system is adjusted properly, making sure the head pipe hanger has proper chassis clearance, the tail pipe is
not contacting the rear axle or chassis, and that the tip is adjusted to preference. Once satisfied, beginning at the front of the
vehicle, fully tighten down all nuts and clamps using a torque wrench. Tighten the nuts using the 15mm socket to 45ft-lb and
the 3.0” clamps to 45ft-lb using the 15mm socket.
