Corsa Twin Silencer Exhaust (TSE3) for '01-'05 E46 330 / 325

All Corsa systems are built to order and require a 10-14 business day lead time.

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.
