The cp-e Hyundai GenCoupe Downpipe from is an amazing piece of exhaust piping that leaves nothing behind in the way of performance and function. The cp-e Genesis downpipe features a stainless steel cast bellmouth, a very unique feature when compared to other downpipes that gives you a single piece of molded metal, formed perfectly to fit the stock Genesis turbocharger. It's very strong and durable and smooth on the inside, allowing great flow and reliable construction. It features an extra o2 bung for those wanting to run an AFR gauge for proper fuel monitoring. From there, the rest of the piping is made of smooth, mandrel bent, 304 stainless steel piping in 3 inch diameter all the way through. A flex joint is also featured to absorb any movement as the car's power is delivered and the pipe moves with the engine. The downpipe connects to the stock or any stock style catback exhaust on your GenCoupe turbo. Noticeable power gains are achieved with this downpipe while maintaining quick spool.
