Beginning after the secondary catalyst, the Track Edition picks up right before the rear axle and provides a full single 3” route from this point and splits to dual 3” tip outlets. The Track Edition has absolutely zero filter, making its sole purpose to increase the volume out of the B48 engine while remaining completely 50-state emissions compliant. A simple cut at the factory cut point is all it takes, and the Track Edition goes into place via four bolt-on components. We include a factory clamp for the cut point that allows drivers to easily swap back to their stock rear section if ever needed. Which option should you go with? Due to the structural differences between the 330i and 430i, we recommend the following configurations: 330i: With all factory emissions equipment in place, the Track Edition is recommended for those wanting an elevated exhaust experience from within the cabin. If you plan to upgrade anything further upstream, consider the Touring Edition. Otherwise, the Touring Edition will resemble stock from within the cabin. 430i: Given the coupe design of the 430i, interior acoustics differ when compared to its sedan sibling, with new frequencies making their way into cabin. Due to this, and with all factory emissions equipment in place, we recommend equipping the Touring Edition to ensure an enjoyable driving experience. Drivers can, of course, equip a Track Edition, but it may be much for some, especially if anything upstream has been changed. You’ve been warned.
