{"type":"firestarter.listing","listing":{"id":"lst_EMaQIpAS","product_name":"GAS Test Pipes - Audi 3.0T Supercharged","category":"Downpipes","description":"As many people know, tuning your supercharged 3.0T beyond just a single pulley setup can drastically shorten the life of your stock catalysts, and even cause engine damage if left alone.\nAfter installing many poor-quality, low-cost imported test pipes, we began development in 2017 of a high-quality test pipe that would last. Our test pipes (like all of our products) are manufactured from start to finish in-house in Ontario, Canada by our certified TIG welders and go through thousands of hours of torture testing on our own 3.0T development vehicles. \nThe result is the highest quality test pipe you will find for the 3.0T.\n \nFeatures:\n\nHand-built using T304 stainless tubing\n10mm T304 stainless laser-cut flanges, welded inside and reinforced outside to prevent common flange warping/cracking\n1/8” T304 stainless mounting brackets \nFully TIG welded and back-purged for strength and longevity\nTrue 2.5” with 2.5” flanges, no tapering down to OEM size, eliminating the bottleneck when running aftermarket downpipes/cat-back\nProven on hundreds of Stage 2+ dual pulley/ported charger setups \n\nZERO failures to date\n\nLifetime warranty\n\n \nIncludes:\n\nTest pipe set\n2x OEM upper gaskets\n2x OEM lower gaskets\nAll required hardware\n\n \nFitment:\n\n2009-2016 Audi B8/B8.5 A4/S4 3.0T\n2007-2017 Audi B8/B8.5 A5/S5 3.0T\n2012-2018 Audi 8R Q5/SQ5 3.0T\n2011-2018 Audi C7/C7.5 A6 3.0T\n2010-2018 Audi C7/C7.5 A7 3.0T\n2011-2018 Audi D4 A8 3.0T\nDoes not fit: C6 A6, 4L Q7, 4M Q7\n\n \nProper software/tuning will be required. These test pipes are for off-road/racing use only.
