Tomorrow we will receive the initial pre orders of the GReddy Supreme-SP system for the Honda EF CRX/Civic.
We will begin shipping as soon as Friday!
Thank you everyone for ordering!
The highly anticipated GReddy Supreme SP cat-back for the 1988-91 Honda CRX has made its return with key improvements. Larger 2.5” (63.5mm) diameter mandrel-bent piping carefully follows an OEM EF-CRX layout and incorporates pre-resonated mid-pipe and longer straight-though SP oval muffler. This classic configuration, with single 2.5” inlet to dual 2.5” outlet piping to 3” double-wall GReddy tips, makes for the classic GReddy looks and sound, that nostalgic Honda owners have been searching for.
