The CTS B7 A4 2.0T test pipe is the premier test pipe for your B7 Audi A4 2.0T. 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. In addition to being one of the best bang for the buck performance upgrades for A4 owners, our test pipe is also a very attractive piece. Our Catback exhaust kit bolts up directly to our test pipe with no hassle so future upgrades are easy.nnProduct Details:nT304 stainless steel constructionnMandrel-bent stainless steelnFully tig welded designnOptional third 02 bungnInstall hardware includednThroaty soundnGreat power upgradennFitment:nnFitment for factory turbo and CTS-TR-1070.n2006-2008 Audi A4 2.0T with manual or automatic transmission.
