Yeah, someone posted that elsewhere. Gives us hope that we have a new company (for us) working on parts. Gains seems to be pretty signifcant as well for just intake/exhaust. Unfortunately I found nothing for the Lancer on their website the times I looked. Only DSM parts are posted as of now. Oh well.

 

I guess 2.5 inch piping isn't too big then

 

I hear that is too big for N.A. motor. A couple of sources tell me 2.25". AROUND THAT IS!
