Titan Motorsports MKV high flow downpipe is designed to increase performance and sound for your MKV Supra. These high flow downpipes are hand-crafted from smooth radius 304 grade stainless steel utilizing CNC flanges before being TIG welded in custom-built fixtures. This is a direct replacement and requires no cutting or welding. Our downpipe is designed to fit the factory exhaust system but can also be utilized with aftermarket catback exhaust systems designed to mate up to the OEM downpipe. Installing this downpipe on its own will provide additional sound, amplifying the cars existing off throttle crackle, as well as an approximately 40whp increase. Combined with custom tuning, this simple modification can yield increases of 100 horsepower and 100 ft/lb of torque. Our Titan ProTune comes equipped with 93 Octane as well as 100 Octane maps to help take advantage of the increase in exhaust flow with a simple map switch. As with all exhaust modifications, this is designed for off-road use only or racing use only.
