Our 3" performance downpipe upgrade replaces the restrictive stock 2.25" diameter assembly and is a great complement to sport cat-back exhaust system. By reducing the exhaust backpressure, our downpipe upgrade will provide a smoother flow of exhaust gases, quicker turbo spool-up, and noticeable performance and audible improvements. A conservative 10hp and 12lb/ft of torque are expected solely with our performance downpipe upgrade, along with a deeper and more pleasant exhaust tone. Our downpipes are manufactured to the highest level of quality to outlast the life of the car. Downpipe components include fully mandrel bent 3” piping (304 non-magnetic stainless steel) and a TIG welded construction for long lasting performance, and a spare O2 bung for air/fuel ratio monitoring and miscellaneous tuning.
