Give your Audi A4 or A5 the sound and performance it deserves with the GCA Performance Valved Sport Exhaust System for the 2008–2017 B8 and B8.5 platform. Designed specifically for vehicles equipped with the 2.0L TFSI turbocharged engine, this premium cat-back exhaust system delivers improved exhaust flow, reduced backpressure, and a noticeably more aggressive exhaust note while maintaining everyday drivability.
Replacing the restrictive factory exhaust allows your engine to breathe more efficiently, helping improve throttle response, turbo spool characteristics, and overall driving enjoyment. Whether you're cruising around town or pushing your vehicle on spirited drives, this exhaust system provides a more engaging and refined driving experience.
The integrated vacuum-operated valve system gives you complete control over your exhaust sound. Keep the valves closed for a quieter, comfortable ride during daily commuting, or open them to unlock a deeper, sportier tone whenever you want a more aggressive presence.
Constructed from premium T304 stainless steel or optional 6AL-4V Grade 5 Titanium, this exhaust system is engineered to withstand extreme temperatures while offering exceptional durability, corrosion resistance, and weight savings. Precision TIG-welded construction ensures outstanding strength, fitment, and long-term reliability.
