CTS Turbo B9 Audi SQ5 High-Flow Cat is made to maximize exhaust flow for highest power gains. Do not compromise performance and sound with factory parts. \n \nDesigned using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from CAST T304 stainless steel; hand TIG welded and back-purged to ensure years of reliable performance. \n \nIn addition to unleashing the power and performance of your 3.0T, the CTS Audi SQ5 High-Flow Cat will make your vehicle sound like an S-car really should. When installed with factory exhaust it produces a sporty growl with much more pronounced exhaust "crackle" on downshift. While up-shifting you will enjoy a confident "braappp!" as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system. \n \nProduct Details: \n
