Unlock the full performance potential of your Audi S4 B9 with the genuine Armytrix Stainless Steel Decatted Downpipe, engineered to maximize exhaust flow, reduce back pressure, and deliver significant improvements in turbocharger response and engine performance.
Manufactured from premium T304 stainless steel, this high-performance decatted downpipe replaces the restrictive factory catalytic converter with a straight-through design, allowing exhaust gases to flow more efficiently. The result is faster turbo spool, improved throttle response, increased horsepower potential, and a deeper, more aggressive exhaust note.
Designed using precision CNC manufacturing and premium welding techniques, the downpipe offers exceptional durability, corrosion resistance, and OEM-quality fitment. It installs directly onto the factory mounting points, making it an ideal upgrade for enthusiasts seeking maximum performance.
Compatible with selected Audi S4 B9 models, including:
- Audi S4 B9 Sedan 3.0 TFSI V6 (354 hp)
- Audi S4 B9 Avant 3.0 TFSI V6 (354 hp)
