COMPLETE HEADERS & DOWNPIPES • STAINLESS STEEL • OFF ROAD SYSTEM
THE HEADER THE AUDI COMMUNITY HAS BEEN ASKING FOR ?
The XS-POWER Audi B6/B7 S4 Long Tube Header System was developed specifically for enthusiasts looking to eliminate the restrictive factory manifolds and finally let the legendary 4.2L V8 breathe.
This complete system includes both headers and downpipes all the way back to the cat-back connection.
No catalytic converters. No unnecessary restrictions. Just maximum exhaust flow and the aggressive V8 sound Audi enthusiasts love.
We have released to the Audi community a new force in cooperation with SSAC and XS-POWER — brands that Audi enthusiasts have known for years.
