To further improve the the flow and performance of your GReddy (FK8) cat-back exhaust for the Civic Type R, GReddy has released this optional full 3" (non-tapered) forward midpipe, that will replace the original Supreme SP (& HG) forward midpipe.
The slight taper in the standard Supreme SP forward midpipe (is designed to mate up to the factory overpipe flange and) more than adequate for use with the Civic Type R factory catalytic converter and factory front overpipe.
When upgrading these units, you may also want to maximize the flow with a full 3" (76mm) stainless steel forward midpipe upgrade. Specially designed flanges and gaskets allow for a perfect match to our emissions friendly (cat-back) 3" Front Overpipe (PN 10558600 sold separately).
