You are looking at the Limited Version of Grimmspeeds Catted Downpipe for the 08-14 Subaru WRX / STI & 2015+ Subaru STi. When looking to get more power out of your Subaru, a downpipe is a great place to start! This replaces your restrictive catalytic converter with a single high-flow unit. This particular downpipe utilizes a divorced design for optimal exhaust flow.
This Limited Version is for the tuner looking to wring out every last ounce of performance and quality! It uses flanges made of the same 1/2" 304L material, but with recesses in each tube that smoothly transitions the irregular shape of your internal wastegate outlet into the divorced tube for tighter boost control.
Not CARB Legal. Off-road use only. Requires a Tune.
