One of Megan Racings strongest products, the Cat-Back System is made of SUS-304 Stainless Steel with a fully polished surface, CNC machined flanges and mandrel bends. Its aggressive styling, and deep, strong tone are just part of the MR Cat-Back characteristics. It also serves to improve horsepower, torque and overall performance with its straight-through design. The exhaust systems have 2.5? piping and 3? piping for certain forced induction models. Finished with a tip that is designed to increase the scavenging effect and achieve maximum performance, while adding a perfect match on exterior styling as well.   We use megan racing parts for our own cars like our Integra Type R DC5, Civic EP3 Type R, Prelude 97, etc. We wouldn?t recommand you these products if we were not fully satisfied about the price & quality ourselves. Series: Drift-Spec (D-Spec) The latest catback system is the drift-spec style. Designed to give it a more agressive look the exhaust is angled up and outward. Depending on each car and each bumper design, the exhaust will vary upon the direction and angle that it sits.   ? 4" tip with 5.5" width muffler ?

It truly is an amazing product and quality is very much up to standard to the more popular brand names. If not even better than some of them. ? Nickname: DARQMX Goddamn that Megan sounds nice and thick... i love it... i bet it is a 3" and i also bet it sounds this good because of the turbo... I hope when I get mine it sounds just as good on a NA car. ? Nickname: 1llmatic In terms of catback exhausts Megan Racing actually has a decent exhaust system. The entire system is full stainless steel compared to other big name brands that only use mild steel piping with a stainless steel muffler. I believe DC sports is one of the only other companies to offer a true full stainless steel exhaust system. (Correct me if i'm wrong) Link to Youtube video?s: Click here.
