A performance turbo downpipe upgrade is a great way to complement your 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.
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), pre-cat flex pipe in AISI 409 stainless steel, original oxygen (O2) sensor and hanging points and a high-flow, Ecocat branded racing catalytic converter (metallic core). A 3” to 2½” after-cat piping coupler allows seamless installation with our sport cat-back exhaust system. Manufacturing facilities are ISO 9001 certified, ensuring the highest quality and safety of all manufactured products. Our Performance Downpipes come with a lifetime warranty against manufacturing defects.
DISCLAIMER: Performance downpipes have not been tested or approved by any international, federal or local governing agency for street use. As such, they are designated for NON-ROAD or RACE TRACK use only, not for sale or use in the state of California. Please research the emissions and legal requirements for your region.
