Active Autowerke BMW E46 M3 Exhaust SECTION 1 with 100 CELL hi flow catalysts (11-110) _(piggy_Back_Style)_Water_Pump_And_Alternator_Pulleys_(3) our Unequal Length Header featuresThe Active Autowerke Exhaust Section 1 for the BMW E46 M3 is designed specifically to address the raspy exhaust note and unburnt fuel smell commonly experienced when upgrading to performance headers on this model. While the factory BMW Section 1 uses a straight through design with built in resonators, this aftermarket section 1 integrates a pair of 100 cell high flow metallic catalysts to filter exhaust gases without sacrificing performance.
