CTS Turbo Performance Downpipes - High Flow Cats - F97 X3 M, F98 X4 M

CTS Turbo High Flow-CATS are made to maximize exhaust flow for the highest power gains. Designed using the latest in CAD technology; this part is made to fit perfectly in place of the restrictive factory catalytic converter. Manufactured from CAST T304 stainless steel; hand TIG welded and back-purged to ensure years of reliable performance. In addition to unleashing the power and performance of your 3.0 Twin Turbo, CTS' 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 a 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.
