No not the R/C car company either. HPI is a Japanese company that makes aftermarket parts. The site has a English section and the staff speaks English so if you need to you can drop them a email. Not a bad company.

the stuff is junk though.......we have done their manifolds on a few DSM's with bad results...tons of cracking

Haven't heard anything bad about them here in Japan. I know somebody running their FMIC kit in his Subaru with no problems at all. Then again if its a DSM its going to break anyways.
