I cut this off of my B16 hatch when I totaled it. It wasn't on for more than a year I believe. I assume it flows very well considering I made 163whp on my B16 with just ITR cams, ebay intake, Megan header, and crush bent 2.5" exhaust with this cat. Anyway, it's a true Catco cat. I'll let it go for $25 plus shipping. Im located in Birmingham, AL. I only deal with paypal. My paypal is hxc4ever@gmail.com
