Product Description

FROM THE MASTERS OF 3.0T PERFORMANCE:

AWE proudly presents the B9 S4 exhaust solution—signature AWE tone, performance, and options for every taste and budget.

THE VALVED SWITCHPATH:

The SwitchPath valved solution gives you complete control of volume and tone at your fingertips. Includes non-resonated downpipes, a precision-engineered X-pipe mid-section, and two valved mufflers, controllable via the factory setup or the optional AWE SwitchPath™ Remote.

Sneak out quietly with the valves closed, or open them to unleash full 3.0T fury.

Comes with 102mm slash-cut, double-walled tips in Chrome Silver or Diamond Black, each featuring the AWE logo and adjustable for bumper depth.

Note: A slight valve rattle may occur at cold start and fade within minutes, just like the factory exhaust.

THE TOURING EDITION:

The Touring Edition removes factory valving and introduces AWE’s drone-canceling 180 Technology resonators and valve simulators. Civil during cruising, aggressive during throttle, with all the crackles you crave.

Note: This system gets rowdy—especially in the midrange and at cruise. Not returnable based on sound preference.

THE TRACK EDITION:

The most aggressive system in the lineup. The Track Edition replaces all resonators with straight pipe sections, keeping only the X-pipe for balance.

Includes non-resonated downpipes and delivers constant volume and raw tone.

Warning: This system gets loud and is not returnable based on sound preference.

Comes with 102mm slash-cut, double-walled tips (Chrome Silver or Diamond Black), AWE logo etched, and individually adjustable.

SWITCHPATH REMOTE:

The AWE SwitchPath Remote offers push-button control over your exhaust valves, bypassing factory Drive Select behavior. Open or close valves at will—anytime, anywhere.

Includes two remotes, control box, and hardware for a plug-and-play installation.

100% EMISSION-FRIENDLY:

AWE Exhausts do not interfere with any factory emissions equipment.

MADE IN PA, USA:

Engineered, designed, and manufactured in-house at AWE using US-sourced .065”-wall T304L stainless steel to achieve a tone deeper than everyone else.

THE FINE PRINT:

AWE’s Perfect Fitment Guarantee, No CEL Guarantee, and Lifetime Warranty all come standard. Track Editions can not be returned for sound reasons (but you can do a conversion kit to Touring Edition at any time!).
