Exhaust System Installation
Double Helixx X-Pipe
2014+ C7/C7 Z06 Corvette
PN 14761
Factory Exhaust System Removal:
1. Remove the factory tunnel under shield. The shield is secured in place by 24 bolts, including two larger bolts
near the front of the shield. Use an 18mm socket and 3/8” ratchet to remove the two larger bolts, followed by a
13mm socket and ratchet to remove the remaining 22 bolts. (Fig. A, B, & C)
2. Remove the four nuts that secure the factory x-pipe inlet flanges using a 15mm socket and 3/8” ratchet. (Fig. D)
3. Remove the two bolts securing the X-pipe hanger grommet with a 13mm socket, a 3/8” ratchet, and a small
extension. This will allow the factory x-pipe section to droop. Set aside these bolts to be reused during the
installation process. (Fig. E (Auto) or Fig. F (Manual))
4. Loosen the clamp bolts at the x-pipe outlet using a 15mm socket and a 3/8” ratchet. (Fig. G)
5. CAREFULLY pivot the stock x-pipe section down at the inlet flanges and then forwards to free it from the vehicle.
(Fig. H)
6. Remove the hanger grommet from the two hangers using grommet pullers or similar device. Set aside the
grommet to be reused during the installation process. (Fig. I)
Note: The use of a soap and water solution may make working with rubber grommets easier.
7. CAREFULLY Remove both of the factory donut gaskets using a small flathead screwdriver. Set aside the donut
gaskets to be reused during the installation process. (Fig. J) This concludes the removal process.
