Installation of CORSA Exhaust System:

NOTE: Apply the anti-seize lubricant (supplied) to the threads ONLY of all the clamps and flange bolts.

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 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 your vehicle.

Note: Using a soapy solution on the hole in the grommets will make

the installation

easier

Locate

the CORSA

XO-Pipe

the

factory clamps over

the

pipe inlets. Slide
