CTS Turbo Audi 3.0T Supercharged V6 Test Pipe set

The factory cats on the supercharged Audi 3.0T V6 are notorious for failing once you raise power output. The CTS Turbo test-pipe set drops straight in where those restrictive catalysts sit ahead of your downpipes, running 2.5" stainless piping with smooth mandrel bends for clean flow.

The payoff is real power, freer-breathing exhaust and a throatier tone. Each pipe is mandrel-bent and hand TIG-welded.

What you get

• T304 stainless steel construction
• TIG-welded by hand
• A strong upgrade or a replacement for worn-out cats
• Beautiful brushed finish
• Gaskets and hardware included for install
• Works with factory or aftermarket exhaust systems
• On RHD vehicles a small dent must be made on the right-side test pipe to clear the steering shaft
