Bull-X 3.5″ downpipe for Audi S1 8X 2.0 TFSI quattro 231 PS

These downpipes are ideal for standard and performance-tuned vehicles. Fitting one of these downpipes increases power and improves throttle response. Another important benefit is the reduction in exhaust gas temperatures, which thermally relieves the turbocharger and surrounding components and reduces their load.

Note: Suitable only for left-hand-drive vehicles.

Advantages:

• increased performance
• reduced load on components
• pipe diameter: upper section 89 mm, continuing at 76 mm after the catalytic converter
• available without a catalytic converter, with a 100-cell sports catalytic converter, with a 200-cell sports catalytic converter, with a Bull-X 200-cell EOBD sports catalytic converter by HJS, or with a 200-cell HJS sports catalytic converter with ECE approval
• material: stainless steel
• TIG welded
• a reducer for connection to the original exhaust system is included

Road use: Only the version with the 200-cell HJS sports catalytic converter with ECE approval is suitable for legal use on public roads. All other catalytic converter versions and the catalytic converter replacement pipe are intended exclusively for track use.

Suitable for: Audi S1 I (8X).
