CrateMuffler™ Installation Guide
*** Required Inlet/Outlet Muffler Orientation ***
Borla Performance Industries, Inc. created the CrateMuffler™ specifically for the high-end hot rod builder market. The Borla
CrateMuffler™ is an industry-first product tailored to specific engine displacement/power ratings. The Borla CrateMuffler™ is as
unique as the engines they’re matched to focusing on terrific sound, optimal performance, improved aesthetics, and minimal high-
way cruising cabin resonance. The materials and construction are Borla-proven T304 stainless steel with an upscale brush-finish
and the Borla Million-Mile Warranty.
Borla Performance engineers spent hundreds of hours fabricating, installing, and sound-testing many prototypes on various popu-
lar vehicle/engine configurations. This process included the available muffler space, typical hanger placement, and overall muffler
aesthetics. During the research and development we tested and evaluated each CrateMuffler™ on engines installed in numerous
vehicle platforms. In summary we optimized each CrateMuffler™ to function in a specific directional-flow of vehicle exhaust.
While your CrateMuffler™ will work if installed in a reverse direction, sound attenuation will be compromised if the ex-
haust flow is reversed.
Please verify the exhaust flow is exiting the ENDPLATE side for the best sound and overall perfor-
mance.
We incorporated visual design elements to help
ensure your CrateMuffler™ is properly installed.
Please refer to this installation guide for plan-
ning and during the installation process.

WELDED
ENDPLATE
The OUTLET TUBE is located on the same
side of the ENDPLATE. The ENDPLATE is
welded-in with a Borla logo displayed when
viewed from the rear of the vehicle.
Whether you have Offset-Center or Offset-
Offset
CrateMuffler™
, you’ll get the best
sound and aesthetic advantages using this
orientation.
The ENDPLATE can be used as a direct-weld
mount for hangers or a removable hanger
mount using Borla ENDPLATE BRACKETS
(available separately*).
Either method ensures a terrific look and se-
cure mount. *Please see pages 2-6 of this in-
stallation guide for further information.
The ENDPLATE can be customized (by the
customer) to match the vehicle in paint or pol-
ishing.
This option allows flexibility to the fab-
ricator for a unique finish to compliment the
vehicle.
