The COBB Tuning Mitsubishi Downpipe features a widened diameter of 3" for increased flow of exhaust gases from the turbocharger to allow for improved horsepower and torque. The downpipe is constructed of 304 stainless steel, mandrel-bent tubing, which can be fitted to the OEM exhaust or the COBB Tuning Test Pipe.
The trailing-end flange uses the stock donut gasket and factory spring bolts to aid in flex, longevity and proper fitment. This provides an improved seal compared to other methods, as well as reduced noise.
