We
designed the E46 M3 muffler section with several
performance goals in mind:
-
deep
tone, suitable to character of the M3
-
exact
factory fit.
-
compatibility
with the original BMW midpipe or UUC Rasp-X.
-
no
change in ground clearance.
-
weight
savings compared to stock system: 39.5lbs
(original is approximately 55lbs)
-
tip
design: 4 x 3" double-walled and polished.
-
legitimate
hp gains (beware of inflated and unrealistic
"marketing" hp numbers from other
offerings!).
-
no
impact on emissions or warranty.
Superior
Materials and design
All UUC
performance exhaust components are built from 100%
T-304 stainless steel. All bends are smooth
mandrel bends to retain full-diameter flow, and all
joints are TIG-welded. Factory-style mounting
flanges are used, and all factory mounting points are
retained. 100% MADE IN
USA
WARNING: Beware of so-called "stainless
steel" exhaust systems using a 400-grade
steel. 403, 404, etc., are grades of steel that
are "stain resistant" but will eventually
rust. This cheaper material is often
responsible for the significant price
differences. UUC uses T-304, a true
"stainless" steel that will never rust.
How
it works
Of the
many ways to design a muffler, sometimes the factory
design is a decent basis. With that in mind, the
UUC M3 Performance muffler follows the original layout
of an entry muffling section, a central mixing
chamber, and then outlet routing to the quad
tips.
The difference in sound and performance is due to the
decreased backpressure and tuned chamber perforations.
