Mitsubishi Evo X Cat Back System

We have designed our 3" cat back rear system with a twin box set up in a Y design which is a far superior design in terms of flow/power over a single box set up. Our Y design rear system also has a weight saving of 3 kgs over standard. The rest of the system is designed to be as straight as possible for maximum flow. 90db or 93db with centre silencer which is optional.
