HKS Introduces New Bellmouth Downpipe for 2008 Subaru WRX and WRX STi



Our friends at HKS USA, purveyors of fine engineered performance products, have introduced a new downpipe for the 2008 Subaru WRX and WRX STi 5-door hatch – Part #33006-BF002; $475 MSRP . As always, adding TRUE performance products will always net in real power additions.

Constructed of a cast-iron bellmouth mated to 75mm SUS304 stainless steel piping, this new HKS downpipe is a direct bolt-on replacement for the restrictive factory downpipe (read: choking point inhibiting power). A newly designed exhaust flange adapter allows the downpipe to bolt up to the factory center pipe, HKS center pipe, or the soon-to-come HKS 75mm full cat-back exhaust system, eliminating all exhaust restrictions.

This new downpipe is designated as OFF-ROAD USE only, meaning it won’t pass emissions restrictions in your local state. So keep it on the track only.
