LG Motorsports LG C6 Z06 Pro Long Tube Headers - Manual (Page 5)

At this point the rest of the system can be loosely hung into place and should look like the
picture in figure 5 once completed.

Before final tighten of all of the clamps care must be taken to insure that all pipes
are located correctly taking special care to note placement of the rear pipes as they go
over the rear end of the car. You have to raise the rear pipes up as far as they can
before tightening the rear clamps. This plus rotating the muffler tail pipes to keep the 3"
muffler pipes away from the frame will solve this. The left muffler has to be rotated
"clockwise" and the right muffler has to be rotated "Counter Clockwise" to clear the
frame. It won't take much but it has to be done. The stock mufflers are also rotated in
this manner to some degree. While tightening the exhaust clamps down make sure that
each clamp is clear of the frame rails, and each other. Special care must be taken on the
clamps around the X pipe as they can rotate too far and the bolt will rattle on the center
plate support. Once the install is complete please give the exhaust a once over and make
sure no pipes are touching, clamps are free of each other and that the bolts are not making
contact with any part of the car. Once the car is complete please drive the car to check
for leaks and any rattles that might pop up after install. The header and pipe fitment is
more critical since the pipes are so much larger so time must be taken to make sure all
pipes are in their right place.
