The CTS Turbo B8/B8.5 Audi A4/A5/AllRoad/Q5 1.8T/2.0T Test Pipe is the premier test pipe for your Audi. Our test pipe is designed to seamlessly fit in place of your restrictive stock catalytic converter, which is situated immediately after the turbocharger. Our test pipe features 3″ stainless steel piping, smooth mandrel bends, two 02 sensor bungs with an option for a third. Substantial power gains, improved exhaust flow and a more throaty sound are the main benefits of installing our test pipe. Upon inspection you will notice a flare which is nearly 4″, this flare then tapers to 3″ and is designed to allow for optimal flow as the exhaust gas transitions from the turbocharger to the test pipe. In addition to being one of the best bang for the buck performance upgrades for A4/A5/AllRoad and Q5 owners, our test pipe is also a very attractive piece. Each 3″ test pipe is mandrel-bent, hand tig welded. Do you need an additional 02 bung for data logging? Well, that’s no problem! Extra O2 bung is now included at no extra charge!

Very nice piece of piping! The hardware included copper plated nuts and gaskets for both ends. My head is currently removed for repair so I cannot comment on turbo outlet fitment but the aft end & mounting tab location matched up perfectly. Oxygen sensor bungs and locations do not interfere with firewall. Can’t wait to fire it up! 2013 allroad, engine code CPM. (waiting for turbo kits to go on sale again…)

Fit was excellent, finish was beautiful. Made a big difference in throttle response, would highly recommend. Cant even hardly tell its catless with the stock exhaust. Bought the rear O2 check engine light eliminator and it worked as advertised. Great product.

Like a whole new car! Amazed with results , just need 90 degree o2 sensor spacer for CEL code

Fitment was A+. O2 sensor placement and alignment to the factory mid-pipe was perfect. This replaced a pipe from flea Bay that broke after a few months and didn’t have enough clearance for the mid-pipe or upstream o2.

Welds are great; fitment is near-perfect, fast shipping and greatly added sound and power. Buy it.

Good quality, sounds good however I do believe that it fits a little odd on my Audi a4 b8.5 (it did say it should fit) and it does however a little undersized on the part where it connects to the turbo
