FIG. J
Installation of dB Exhaust System:
NOTE: The supplied double edge clamps in this system will crush and permanently
deform the exhaust piping as they are tightened. DO NOT tighten these clamps any
more than is necessary to lightly hold the exhaust components in place, until the very
end of this installation process. It will be difficult or impossible to make any positional
or rotational adjustments to the exhaust system after these clamps have been
tightened down.
VERY IMPORTANT: Align all the clamps so that the open edge of the clamp bracket is
parallel and aligned with the notch in the pipe, and the outside edge of the clamp
bracket is approximately 1/8” from the end of the pipe expansion. (See Fig I) Failure
to properly position or orient the clamps could result in a weak clamping load, or even
a potential leak at the clamp joints.
IMPORTANT: Make sure that the small drain holes in the muffler are facing down
when the muffler is installed.
1 Locate the headpipe assembly and slide the spherical clamp over the studs on the
factory spherical clamp. Use the nuts supplied with the hardware kit and loosely
snug. Insert the hanger into the factory grommet. (See Fig’s K & L)
Note: Using a soapy solution on the grommet hole will make the job easier.
2 Slide a supplied 3” clamp over the inlet of the DB Muffler. Make sure the weep
hole is facing down then slide the muffler onto the headpipe and pre-tightened the
clamp. (See Fig’s M, N & O)
