For sale is a (used) Prodrive diff-back exhaust with the oval tip, like here:

This exhaust uses 2.5" piping and I've switched over to a diff-back with 3" piping... hence the sale.

Currently a step-down (or step-up, depending on which way you're looking at it) reducer has been welded at the mid-pipe end of it so that it can bolt straight up to a 3" mid-pipe, so depending on your application you may need to chop that off and just have a short straight 2.5" piece (w/flange) welded back on.

Note that anything larger than a TD04/2L combo may lose a bit of power when using the 2.5" piping in the rear. I'm running with a VF34 now which is why I changed to 3" all the way through.

This is such a great sounding muffler and deserves all the praise that it's received on sites like NASIOC. Deep tone but discreet, and I never experienced any boominess/droning inside the car (2003 WRX sedan).

SOLD!!!

Please PM with any questions

Cheers - Nik
