The CTS B6 A4 1.8T test pipe is the premier test pipe for your B6 Audi A4 1.8T. 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 from installing our test pipe. Upon inspection you will notice smooth mandrel bent piping with seamless transitions from the turbocharger to the exhaust system. In addition to being one of the best bang for the buck performance upgrades for A4 owners our test pipe is also 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!

Nice Build Quality As Well As The Hardware Provided, Easy Install If You Take Extra Time To Pull Off The Pipe After The Cat To Reach All The Bolts On The Back Of The Cat!

the only reason it will get 4/5 stars is because the downpipe does not fit on my axle shield so i need to do some custom work or buy something else from u guys which is a bummer i thought it would fit. other than that the downpipe is amazing it sounds great it gives me noticeable power upgrades and it’s still sealed great!!!
