THE #1 EXHAUST FOR THE AUDI S4.

The exhaust system that started it all. Engineered specifically for Audi’s 3.0T, the AWE S4 exhaust pioneered our drone-canceling 180 Technology®. Choose from refined Touring or aggressive Track Editions, plus optional Resonated or Non-Resonated Downpipes.

THE TOURING EDITION:

The Touring Edition delivers refined cruising with aggressive tone at wide-open throttle, thanks to AWE’s patented 180 Technology®. Handcrafted in the USA from T304L stainless steel, it offers precision, performance, and unmatched sound quality.

Note: Factory downpipes may occasionally produce minor rattling when paired with this exhaust; upgrading to AWE downpipes eliminates this issue.
 

THE TRACK EDITION:

The Track Edition provides maximum volume and aggression by eliminating the 180 Technology® mufflers found on the Touring Edition. Constructed from the same T304L stainless steel and offering identical performance gains. Loud, rowdy, and ideal for enthusiasts.

Warning: Particularly loud at part throttle for S-Tronic models. Track Editions cannot be returned based on sound preference, but easily convert to Touring Edition with an AWE Conversion Kit.

Note: Factory downpipes may occasionally produce minor rattling when paired with this exhaust; upgrading to AWE downpipes eliminates this issue.
 

DOWNPIPES:

Optional Resonated and Non-Resonated Downpipes are 50-state compliant and refine the sound further:
 

• Resonated: Recommended for S-Tronic models; delivers a smoother, mellower sound.
• Non-Resonated: Offers a louder, aggressive exhaust note.

Downpipes feature larger-than-stock diameter tubing and pair seamlessly with AWE or factory exhaust systems.

LET’S TALK TIPS:

Both Touring and Track Editions include adjustable 102mm slash-cut tips with the engraved AWE logo. Each tip is double-walled to maintain a mirror finish, even under intense driving conditions.
 

NEVER STUCK WITH AWE CONVERSION KITS:

Want a different tone later? Conversion Kits let you switch between Touring and Track Editions without buying a new exhaust. Simply unclamp, swap sections, and enjoy.
 

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!).
