Exhaust System Installation

2014-Current C7 Corvette
PN’s 14762, 14763, 14764, 14765
Polished & Black Quad 4.5” Pro or Poly Tips
5. Reinstall the factory valve control units using an 8mm socket and ¼” ratchet. Both axle pipes should now appear as
shown, with the valve control units reinstalled, and each of the clamp on elbows installed properly. (Fig. F)
6. Install each axle pipe back into the chassis as shown, making sure to reconnect the AFM valve wire. Slide the axle
pipe inlets into the x-pipe section as far as possible (the locating tabs on the factory axle pipe will contact the x-pipe
outlet edge). Rotate the axle pipes until they are centered between the chassis and the transmission components,
then snug the clamps at the x-pipe outlet using a 15mm socket and a 3/8” ratchet, leaving them loose enough for
further adjustment. (Fig. G, H, & I)
7. Reinstall each of the rear muffler hanger grommets as shown using a 13mm socket and a 3/8” ratchet. (Fig. J)
When connecting to a factory NPP exhaust; continue to step 8. If you’re connecting to the factory base exhaust,
skip to step 9.
8. Tuck each of the rear (non-AFM) valve wires into the chassis. They will no longer be needed. Secure with a zip tie
or equivalent. (Fig. K)
NOTE: The driver side muffler needs to be installed first, as the driver side tie bracket sits further forward in the
vehicle. The passenger side tie bracket will nest inside of the driver side bracket.
9. Locate the driver side rear muffler assembly, and one of the 2.75” clamps. While holding the assembly with the
muffler case seam pointed up as shown, position one of the 2.75” clamps such that the clamp bolt is to the bracket
side (inside of muffler) and the nut is towards the ground. (Fig. L)
10. Insert the driver’s side hanger into the rubber grommet as shown, then slide the expansion on the muffler inlet
over the outlet of the clamp on elbow. Secure the clamp with the 15mm socket and 3/8” ratchet, and a long
extension, leaving it loose enough for further adjustment. (Fig. M, N & O)
Note: The use of a soap and water solution may make working with rubber grommets easier.
11. Repeat Steps 9 & 10 on the passenger’s side of the vehicle. Both of the mufflers will still be free to rotate and move
at this point, as the muffler tie brackets are not yet connected. (Fig. P, Q, & R)
12. Locate the tie bracket hardware: 2 M8 flange bolts, 2 lock washers, the half round spacer, and the 2 M8 serrated
flange nuts. Pre assemble the lock washers onto the M8 flange bolts as shown. (Fig. S)
NOTE: The lock washer must go on the flange bolt side to function properly. The serrations on the flange nut will
provide the locking feature on the opposite side.
