  1. Excellent Fitment

    Posted by Thomas Teal on

    Very easy to install, great fitment, includes all hardware. This catalytic converter bolts up well with any 3" header and catback (any ISR/ISIS product). Does not rattle when accelerating, very quiet! (My application was an S13 240SX)

  2. Very Easy Install

    Fitment was on point. The most difficult part of the install was removing the original cat bolts (super rusty).

  3. 3" Cat Review!

    Posted by Unknown on

    Ordered this for my son's daily '93 S13. Installed easily within 20 minutes. Would recommend getting lock washers though. Worked like a charm and quieted down his dual 3" blast pipes a little. :-) Will order another for my other son's '95 S14 soon!

  4. Nice Cat!

    I picked this up to put on my daily S14. Installed in minutes and comes with all required hardware and gaskets.
