Description
Will this cat-back system be 50-state legal?
This 50-state legal Cat Back design ensures compliance across the nation, offering a potent sound without compromising emissions standards.
How is the sound controlled?
SwitchPath technology expertly utilizes factory valving, retaining your M-Sport button functionality for seamless, driver-commanded exhaust note adjustment.
AWE Cat-Back SwitchPath for your 2015-2020 BMW M3/M4 achieves an impressive 9/9 for Exhaust Note/Sound, transforming your driving experience. Featuring 102mm double-walled, slash-cut tips and a 3 inch CNC mandrel-bent configuration for maximum flow, this cat-back system offers unparalleled performance and an aggressive aesthetic.
What Owners Say
Owners and enthusiasts consistently praise the AWE SwitchPath for its exceptional build quality and versatile sound character. With valves closed, it delivers a deep, throaty tone without highway drone, while valves open produces an aggressive growl that transforms the driving experience. The system eliminates the stock "lawnmower" startup noise in favor of a refined rumble. However, some users report notable low-mid range drone when paired with non-resonated midpipes, suggesting careful consideration of your full exhaust configuration. When coupled with downpipes, owners describe the tone as near-perfect. The SwitchPath has earned strong respect among the BMW M community for delivering genuine performance exhaust sound with daily drivability.
