{"type":"firestarter.listing","listing":{"id":"lst_2PnJdaVL","product_name":"GAS High Flow Cats - 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.\n \nAfter installing many poor-quality, low-cost imported test pipes, we began development on 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. \nThese high flow cats feature the same perfect fitment as our catless versions, but are 100% EPA compliant and do not require O2 spacers.  \nThis is the solution you've been waiting for! Stop sacrificing HP for emission issues and check engine lights.\n \nFeatures:\n\nThick-wall 1.6mm 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 hand-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\nHigh quality 400-cell GESI dual S-wound sport cats rated at 500bhp each\nProven on hundreds of Stage 2+/Stage 3 dual pulley setups over 540whp/660bhp\n100% EPA-compliant\n\n\n \nIncludes:\n\nHigh flow cats\n2x OEM upper gaskets\n2x OEM lower gaskets \nAll 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 \nPlease verify fitment on your application before ordering!\nWhile our high flow cats are EPA certified, always consult your local emissions laws before ordering!
