Beginning after the secondary catalyst, the Touring Edition picks up right before the rear axle and provides a full single 3” route from this point and splits to dual patented drone-canceling 180 Technology™ resonators, followed by 3” tip outlets. Given the straight-through design and lack of packing material, the 180 Technology® resonators’ job is to defeat drone prone frequencies that would otherwise be experienced within the cabin. Maximum flow is maintained and exterior volume is increased with the interior experience being much more sophisticated and tame. The package is completed with dual 4.5” slash-cut, double-walled tips, available in chrome silver or diamond black. Crafted in PA, USA, from US-sourced .065”-wall T304L stainless steel, every aspect is meticulously engineered, designed, and manufactured in-house at AWE. Backed by AWE's Lifetime Warranty, No CEL Light Guarantee, and Perfect Fitment Guarantee.We recommend the following configurations--330i: if you plan to upgrade anything further upstream, we recommend the Touring Editon. If you're keeping everything stock, note the Touring Edition will resemble stock from within the cabin on the 330i sedan, and you should consider the Track Edition. 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..
