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. Why twin silencers? The 328/323 models are notoriously "quiet" cars, lacking in the agressive exhaust note typically indicative of a performance car. Our unique Twin Silencer system brings out the "growl" in the beast! The result is power you can feel and a sound that will make you smile. But there's even more that makes the UUC Twin Silencer Exhaust special: weight savings: the UUC TSE is 20lbs. lighter than the original exhaust section removed. extra ground clearance: got a lowered car that scrapes the muffler on the ground? The TSE's silencers sit higher than stock. extra tire clearance: planning on fitting super-wide 255, 265, or even 275 tires? The TSE silencers do not intrude into the wheel opening.
