Beyond sound suppression the OEM intake resonator also hinders flow with its disruptive multi-directional flow path. This obstructive factory component is instead replaced by 76mm diameter, durable, and lightweight smooth-bore aluminum piping that improves flow for increased turbo efficiency. The black powder coated piping incorporates TIG welded fittings that guarantee seamless fitment with the factory connections in and a nearly concealed aesthetic within the engine bay. Whether or not you are running completely stock or with a variety of 3rd party modifications the Dinan assembly will fit right in. Short of the tempered, outlined, DINAN logo peeking out from just underneath the cowling you will be hard pressed to even realize it's there - that is, until you hear it.
