HicksZ Posted February 19, 2004 Report Posted February 19, 2004 I don't post here often but Ive been a member for a little while. I was searching through Summit for a replacement cat(high-flow preferred) for my 92 Z-34. I wasnt positive on the fit(2 1/2"?), and I checked applications for any that listed Chevy and found no Luminas. I was checking for Cat-co direct fit. Do I need to get a universal cat and get it welded on? Or is there anyone that makes a Z34 specific cat? Quote
Crimson Fury Z Posted February 19, 2004 Report Posted February 19, 2004 measure the pipe's diameter, and look for a match or the size closest to your measurement Quote
SmoothSteve3 Posted February 20, 2004 Report Posted February 20, 2004 Dont quote me on this, but i think that my 90' lumina 3.1 has 2.5 inch tubing before the cat, and 2.25 inch tubing after it. Not 100% sure though.... Quote
