This is our brand new exhaust shroud cover for the 09-up Nissan R35 GT-R. It is made with a twill weave pre-preg dry carbon fiber, finished off with a UV resistant clear coat. Dry carbon fiber is made in a pre-preg and dry process which consists of vacuum forming sheets of carbon fiber into a mold at temperatures around 350° F, sometimes referred to as an autoclave. This process allows carbon fiber to form into a strong and lightweight composite. Like most race car parts. With a show car shine, this product is immune to UV rays, and will not yellow over time. These will fit over the OEM exhaust panel area when installed.
