The Ultimate Twin Silencer
Exhaust - another UUC Motorwerks first!
The very first exhaust system
for the 328i/Ci and 323i/Ci featuring two completely separate silencers
for optimum flow and awesome sound.
The all-new TSE3 is the absolute best performance exhaust system for
'00-'04 330, 328, 325 and 323 models (i, Ci, iT - not for Xi). It
continues the fundamental design of TSE2 as a full dual cat-back
design,
however the TSE3 is unique in the use of exclusive RSC (Reflective
Sound Cancellation) technology that is capable of targeting and
modulating specific sound frequencies.
The result of this technology is a drone-free exhaust system,
delivering a pleasant sound at idle and cruise and a muscular roar at
high rpm. Test vehicles for this development program included the 330i
Steptronic, whose transmission programming "lugs" the engine at low
rpm, resulting in a high potential for drone. The TSE3 is tuned
specifically to counter that situation and the results are impressive.
How does it work?
Reflective Sound-CancellationT (RSCT)
- a non-electrical noise control system without the complication of
incorporating the use of electronics or speakers. Essentially, engine
sound (pressure) waves are reflected in passages inside the muffler to
cancel out unwanted sound waves. The result is a "tuned" muffler that
"cleans up" the noise without eliminating the pure sound of power
associated with a high-performance vehicle. Using this technology, the
stainless steel RSC mufflers are tuned to eliminate passenger cabin
resonance and produce just the "right" sound. .
The RSC muffler design does not use conventional packing materials, and
provides a totally un-restrictive exhaust flow for maximum power output.
The TSE3 is fully emissions-legal in all 50 states.
Construction enhancements include 100% mandrel-bent pipes, TIG-welded
seams, and true bolt-on installation (no cutting or welding required).
| SOUND LEVEL CERTIFICATION |
Many statutory bodies around the world
currently mandate that vehicles comply with stationary exhaust noise
tests specifications - Generally based upon the "SAE J1169 Measurement
of Light Vehicle Exhaust Sound Level under Stationary Conditions".
California and various other states now have legislation that makes
exceeding this limit an offense, resulting in a "fix it" ticket and
required testing certification.
TSE3 has been certified to meet the SAE J1169 sound test for 95dB noise
limits.
The test involves positioning a type 1, SIA compliant ANSI S1.4 - 1983
noise level meter, specifically as illustrated in the diagram below.
Positioning is relevant, the tests are extremely specific in their
scope and must be conducted under controlled conditions.

Power gains
Dyno results for the TSE3 show useful increases in mid-range torque and
high-end horsepower.

Another UUC Motorwerks first!
UUC offered the very first exhaust system for the all 330 / 328 / 325 /
323 models featuring two completely separate exhaust paths for optimum
flow and awesome sound. On 328 and 323 models, the car is converted to
a true dual exhaust system like the 330 and 325.
The basic BMW design of the exhaust manifold
and catalytic converters does a really great job muffling all the sound
coming out of the motor. But who wants to drive around in an electric
golf cart? Other aftermarket exhausts for the E46 3-series are simply
rear muffler sections which leave both restrictive sound-deadening and
power-robbing resonators in place. Unfortunately for owners of these
cars, the result is little more sound than stock, and very little
performance gain.
The result is power you can feel and a sound that will make you smile.
But there's even more that makes the UUC TSE3 special:
weight savings: the UUC TSE3 is substantially. lighter than the
original exhaust section removed.
extra ground clearance: got a lowered car that scrapes the muffler on
the ground? The TSE3's silencers sit higher than stock.
extra tire clearance: planning on fitting super-wide 255 or even 265
tires? The TSE3 silencers do not intrude into the wheel opening.
