down until they meet each other, then simply install the screw and flat nut to lock
in the connection. In the situation where the variable exists side to side the most
common result is that after the installation has been achieved an unsightly gap can
appear at one end or the other. Keeping in mind that the new panel has been laser
cut perfectly symmetrical, should any intolerable gaps appear, the best and most
sure way to achieve a pristine end result is to stop at an exhaust shop and have the
exhaust perches aligned so as to receive the symmetrical holes in your new panel
and achieve a beautiful and perfectly gapless appearance. The adjustments can be
made at these four perches. Should you elect to perform any adjustments yourself
instructions are as follows: Each muffler has two steel hanger pins. These pins can
be easily bent left or right, up or down. In order to do this you must slide the
rubber grommet off the pin only and NOT completely off the hanger bracket.
With the pins exposed you can adjust them by bending their direction up, down or
side to side as needed. NOTE: Keep in mind that bending the pins will cause the
muffler to move in the opposite direction. The easiest way to bend the pins is by
placing a 16mm deep socket with a long extension over the pins end and using its
leverage to bend the pins in any direction needed. Once you have made your
adjustments simply push the grommet back into place. This procedure will
reestablish the muffler and tip to its desired symmetrical position. TECH TIP:
Although it is a little messy application of a lubricating spray will make it much
easier to remove and replace the rubber grommet.
Special information concerning the 2008 C-6 corvette NPP exhausts system.
The 2008 corvette outfitted with the NPP exhaust system utilizes the
prior years Z06 vacuum actuated muffler and tips mated to a newly
designed manifold/cat system that is ½ to ¾ longer. As a result the
NNP configuration forces the system to sit slightly lower then the
previous years Z06. In order to install the ACC stainless steel exhaust
port filler panel both the all stainless design as well as the newer
heaver perforated design and the laser cut design, Special adjustment
instructions must be performed. What these instructions will explain
is how to easily reposition the muffler and tip system to allow the
panel to fit. Currently these instructions have been 100% successful
and are as follows.
