For those who like it raw, rowdy, and light (drivers can expect an 11 lb weight savings compared to stock), the AWE Track Edition is for you. The Track Edition comes equipped with bullet resonators in the mid-pipes, and shares the same bespoke stainless steel stamped merge and precision engineering as its Touring Edition counterpart, minus AWE’s patented drone-canceling solution, 180 Technology®. In place of the 180 Technology® resonators in the rear are dual Track Edition straight sections. As a result, this version is known to get (really) rowdy in mid-range acceleration and deceleration and may be too much for many. Due to this reason, AWE Track Edition Exhausts cannot be returned based on sound preference. You've been warned! However, AWE made it easy to convert between Track and Touring Editions if you decide at a later date to change your volume.This version of the exhaust keeps your OE tips in place, for that OEM look - super stealth. Presenting the AWE Track Edition Exhaust for the BMW G2X M340i and M440i.
