CTS Turbo BMW F97/G01 X3M/X3M Competition and F98/G02 X4M/X4M Competition High Flow-CATS are made to maximize exhaust flow for highest power gains. \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 3.0 Twin Turbo, our High Flow-CATS will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust "crackle" on downshift. While up-shifting you will enjoy a confident "punch!" 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
