Overview

GFC Mid-to-Rear Exhaust System (Dual Mufflers, Dual Electronic Valves, Quad Tips)

For Audi S4 3.0T (2018)

Mid-to-Rear Exhaust | Dual-Valve Sound Control | Quad Outlets | Premium 304 Stainless Steel & Lightweight Titanium Alloy

Upgrade Your Audi S4 B9 3.0T with High-Performance Flow and Precision Dual-Valve Sound Control.

Engineered specifically for the 2018 Audi S4  powered by the robust 3.0L turbocharged V6 EA839 engine, this GFC mid-to-rear exhaust upgrade optimizes exhaust gas evacuation while sharpening your sports sedan’s acoustic profile. Designed with a custom dual-muffler architecture and integrated dual electronic valves, it allows you to transition smoothly from a civilized, drone-free daily cruise to a deep, aggressive V6 sports exhaust note at the push of a button.

Completed with Aggressive Quad Outlets and Dual Material Options Formed to match the signature quad-tip rear valance of the S4 performance lineup, this system reduces backpressure to improve turbo spool and throttle response. Built in your choice of premium 304 stainless steel for rugged durability or lightweight titanium alloy for maximum weight savings and an enhanced metallic resonance.

DETAIL

🔥 Key Feature

  • Dual Mufflers with Dual Electronic Valves Features a balanced dual-muffler layout paired with dual electronic valves to give you precise, independent control over your exhaust flow, volume, and tone.

  • Dual-Mode Acoustic Versatility Keeps the exhaust quiet and refined during daily commuting when the valves are closed, while opening up wide to unleash a deep, sporty V6 turbocharged growl under acceleration.

  • Signature Quad Tip Outlets Equipped with four matching exhaust tips that fill the factory rear bumper cutouts perfectly, delivering an authentic high-performance athletic aesthetic.

  • Dual Material Choices (Stainless Steel & Titanium) Offered in high-grade 304 stainless steel for robust longevity or premium lightweight titanium alloy to significantly drop vehicle weight and enhance exhaust resonance.

  • Optimized Mid-to-Rear Flow Replaces restrictive factory piping from the mid-section back to reduce backpressure, improve exhaust scavenging, and sharpen power delivery across the RPM range.

  • Precision TIG-Welded Finish Expertly hand-welded using TIG techniques to guarantee smooth internal gas transitions, structural strength, and a reliable, leak-free seal.

  • Direct Bolt-On Factory Fitment Engineered to match factory mid-pipe connection points and OEM mounting hanger locations, ensuring a precise fit tailored specifically to the Audi S4 B9 layout.
