CTS Turbo B8/B8.5 Audi A4/A5/AllRoad/Q5 2.0T Non-resonated Downpipe

Open up the exhaust on your B8/B8.5 Audi A4, A5, Allroad or Q5 2.0T with the CTS Turbo non-resonated downpipe. It drops straight in where the restrictive factory front muffler pipe sits — immediately after your catalytic converter, test pipe or high-flow cat (factory part #2 in the diagram) — for freer flow and a noticeably throatier tone.

Built to last

• 3" T304 stainless steel with smooth mandrel bends
• Stainless core-interlock steel flex section for proper exhaust movement
• Fully hand TIG welded for perfect fitment and longevity
• Removes the factory resonator for a more aggressive sound
• Will not trigger a CEL and removes no factory emission-control devices

Works with your setup

• Compatible with factory cat, aftermarket test-pipes or high-flow cats
• Pairs with stock or aftermarket exhaust systems
• Fits both LHD and RHD vehicles
