Exhaust System Installation
Double Helixx X-Pipe
2014+ C7/C7 Z06 Corvette
PN 14761
Installation of CORSA Exhaust System:
NOTE: Apply the anti-seize lubricant (supplied) to the threads ONLY of all the clamps. 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. Locate the CORSA double Helixx X-Pipe assembly, along with the factory donut
gaskets retained from the last step in the removal process. Slide the donut gaskets onto the X-Pipe inlet as shown,
until they are seated against the flanges. (Fig. K)
2. Insert the X-pipe hangers into the factory rubber grommet as shown. The mounting bracket on the grommet must
be oriented as shown, with the mounting holes facing forwards and favoring the top of the assembly. (Fig. L)
Note: The use of a soap and water solution may make working with rubber grommets easier.
3. Locate the two 2.75” clamps; place them over the outlets of the X-pipe assembly, with the clamp bolts on the
outside facing downwards. Slide the outlet end of the X-pipe onto the axle pipes, then align the inlet with the stock
mounting flanges. Support the assembly with a jack stand or similar device. (Fig. M & N)
4. Locate the flange mounting hardware. Align the stock flanges, and install the hardware, with the M10 nuts on the
downstream side of the connection. Leave the hardware loose at this point.
5. Install the two bolts to mount the X-pipe hanger grommet. Make sure the mounting bracket is centered, then
secure with a 13mm socket and 3/8” ratchet. (Fig. O (Auto) or Fig. P (Manual))
6. Remove any under support(s) at this time. Tighten the four sets of M10 nuts bolts to secure the factory x-pipe inlet
flanges using a 15mm socket and 3/8” ratchet. Alternately tighten each side to keep the x-pipe assembly centered
in the cavity. Verify that the assembly is centered by checking the clearances to the transmission and the X-pipe
outlet. There should be at least a fingertip worth of clearance on both sides (at the closest points to the
transmission and the chassis). Torque fasteners to 31 Ft-Lbs. (Fig. Q)
7. Tighten the clamp bolts at the x-pipe outlet using a 15mm socket and a 3/8” ratchet. Torque bolts to 45 Ft-Lbs.
