Exhaust System Installation
Valve Back Exhaust System
2014+ C7 Corvette (2017 GrandSport Auto)
PN’s 14762, 14763, 14764, 14765
Polished & Black Quad 4.5” Pro or Poly Tips
13. Rotate the rear mufflers upwards until the hole sets align in the muffler tie brackets. Load the two M8 flange bolts
and lock washers in from the front. Place the half round spacer onto the bolts from the backside, so it sits inside
the “V” shape of the passenger side tie bracket. Hand tighten the M8 flange nuts onto the half round spacer as
shown to finish the connection. (Fig. T & U)
NOTE: Make sure the lower step on the passenger side tie bracket is fully inside of the channel made by the
driver side bracket. (Reference the Arrows in Fig. U)
14. Reinstall the rear fascia onto the vehicle. CAREFULLY align each of the locating tabs along the top edge of the rear
fascia. Snap the two corner tabs into place. (Fig. V, W, & X)
15. Reinstall the six bolts that secure the top of the lower fascia (2 on each side & 2 in the center) using a 10mm socket
and 3/8” ratchet. (Fig. Y & Z)
16. Reinstall the two bolts above the tip location using a 10mm socket and 3/8” ratchet. (Fig. AA)
17. Reinstall the ten bolts that secure the bottom corners of the lower fascia (5 per side) using a 7mm socket and 1/4”
ratchet. (Fig. BB & CC)
18. Locate the Corsa tip assembly, along with the two 2.75” clamps (packaged inside tip box). Align both clamps on
the tip inlet as shown, with the clamp bolts to the inside and the clamp nuts facing downwards. (Fig. DD (Quad Pro
Tips) or Fig. EE (Poly Tip))
19. CAREFULLY insert the tip assembly into the cutout in the rear valence. Align the tip assembly inlet with both
muffler outlets before sliding it into place as shown. (Fig. FF & GG (Quad Pro Tips) or Fig. HH & II (Poly Tip))
20. Adjust the position and depth of the tip assembly until it is centered in the cutout, and has an equal amount of
reveal on each side, then snug the clamps using a 15mm socket and 3/8” ratchet, leaving them loose enough for
further adjustment. (Fig. JJ)
21. Reinstall the license plate. (Fig. KK)
22. Reinstall the two reflectors on each side by snapping them back in place. (Fig LL)
23. Reinstall the two lower mesh inserts on each side by snapping them back in place. It is easier to snap the inner tabs
in place before the outer tabs. (Fig MM)
24. Adjust the system accordingly to maximize chassis clearance while positioning the tip assembly within the bumper
valence. Verify that the valved axle pipe assemblies are not contacting anything within the chassis. Starting at the
front and working backwards, tighten the clamps to 45ft-lb using the torque wrench and 15mm socket, ensuring
that the tips are still in the desired position.
