UUC/Corsa TSE3 exhaust for BMW E46 3-Series

The all-new TSE3 is the absolute best performance exhaust system for '99-'06 E46 330, 328, 325 and 323 models (i, Ci,  iT - not for Xi).  The result of the UUC and CORSA partnership 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. CORSA tuned the TSE3 specifically to counter that situation and the results are impressive.

This is the very first exhaust system for all 330 / 328 / 325 / 323 models featuring a  full cat-back design* and 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.

* Full cat-back design means everything under the car.  All 330 / 328 / 325 / 323 models have catalytic converters that are built into the exhaust manifold, there is no emissions equipment after the manifold.  This means that everything after the manifold can be tuned for performance and sound.  Most aftermarket systems are just a rear muffler or rear 50% of the exhaust system and are not complete "performance" exhausts at all.
