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.
Here is a quick overview of the features and
advantages of the ENDPLATE on your
CrateMuffler™:

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.

CrateMuffler™ Touring Resonator Option
CrateMuffler™ Installation Guide
*** TOURING RESONATOR OPTION ***
At Borla Performance Industries, Inc. we understand what you hear in the exhaust note (engine sound and sound pressure levels) is
a subjective topic. While we can identify and minimize unwanted cabin resonances, the loudness or Sound Pressure Level (SPL) is
always a topic of discussion with a final decision determined by the vehicle owner.
Vehicle exterior SPL is measured in decibels (dB) using a calibrated instrument at a set distance, angle, and height from the ex-
haust system outlet. An interior SPL reading is a more complex measurement typically from the drivers seat using head-mounted
microphones. Frequencies vary throughout the rpm band and these variations at higher SPL may cause uncomfortable resonances
in the cabin. A solution to remedy this resonances is often fixed adding more muffler to attenuate the sound.
If you want to lower the SPL of your new CrateMuffler™, you can install the Borla Touring Resonator Option. The Tour-
ing Resonator Option is designed to attenuate overall sound. This is perfect for customers looking to reducing the sound level
2-3 dB(A). This straight-through design will not degrade the performance of your vehicle.
The Borla Touring Resonator Option is available in the same tubing diameters of your CrateMuffler™ and constructed in T304
stainless steel, and backed by the Borla Million-Mile Warranty. Borla recommends welding (not clamping) the Borla Touring Res-
onator Option for final installation.
The BORLA TOURING RESONA-
TOR OPTION is available in 2.25”,
2.50”, and 3.00” tubing diameters. The
outside diameter is 4.00” as it is designed
to fit in the tight spaces of the current
exhaust path. These are designed to be
welded (not clamped) for installation and
positioned in front of the CrateMuffler™
as shown.
