How to Install a Corvette C5 Exhaust

General Motors released the first Chevrolet Corvette in 1953. Production of the 1953 Corvette took place in Flint, Michigan, and over the following decades new generations of the Corvette went into production. The fifth generation Corvette was made from 1997 to 2004 and is considered the largest redesign of the sports car since the original, according to Edmunds. Known as the C5, the fifth generation included a brand new all-aluminum third generation LS1 engine, as compared to the V8 included in the fourth generation. C5 owners have an option of installing aftermarket components like exhaust for further performance gains.

Instructions

Removing Stock Exhaust

1

Open the hood and disconnect the vehicles battery using your socket set.

2

Lift the car off the ground using a floor jack. Refer to the owner manual for the correct floor jack mounting positions. Secure the car off the ground with floor jacks.

3

Remove the four bolts mounting the swaybar in place underneath the vehicle. The swaybar is located near the rear of the transmission and runs across the undercarriage horizontally. Place the sway bar and mounting hardware off to the side.

4

Unbolt the dual muffler assemblies from the catalytic converter extension pipes at the 2-bolt flanges using a socket set. The flange location is located in between the catalytic converters and mufflers near the rear of the vehicle. The muffler assembly will now hang loosely, still connected to the exhaust hangers and rubber insulators.

5

Remove the rubber insulators holding the muffler assembly in place and place off to the side. Lift the muffler off the hangers and remove. Be sure every bolt securing the dual assemblies in place is removed.

Installing New Catback System

6

Refer to the installation instructions included with your new exhaust system before fitting the new muffler assemblies back into the previously uninstalled rubber insulators. At this point, the muffler assemblies will hang loosely from the rubber insulators and hangers. The new muffler fasteners and clamps should not be tightened until final adjustment.

7

Install the drivers side pipe linking the muffler assembly to the 2-bolt flange that connects to the catalytic converter. If a gasket is provided, install it between the new pipe and 2-bolt flange. Reinstall the OEM fasteners removed from the flange previously. Then install the matching passenger side pipe in the same fashion.

8

Move the new exhaust components into place, at least a -inch from any body panels, and tighten all newly installed bolts, fasteners and clamps evenly from front to rear. Refer to the installation instructions for all bolt, fastener and clamp locations and torque specifications.

9

Reinstall the four swaybar mounting bolts, securing the swaybar in place.

10

Reconnect the vehicle battery and turn on the vehicle. Listen for any exhaust leaks, which may sound like hissing anywhere two separate pipes mate together.
