Need Advise on Cats - ZR-1 Net Registry Forums

Aurora40 · 02-10-2008

My impression is the metal matrix cats flow better than traditional ceramic ones? I'd guess they aren't as efficient though, or manufacturers would be using them instead of ceramic ones.

Mine do not have any heat-shielding. They are slip-fit on the headers and flanged to the exhaust. Marc H. did the work.

I don't know how they fair in VA's emissions test as I have not yet had to go with this configuration. Will you be retaining AIR and EGR?
