Z1 HFCs, and Test Pipes IN STOCK!!!
We hope to have Z1 HFCs back in stock very soon, and in most cases we can price match advertised prices.
Are the Z1 HFC back in stock? Do they cause a CEL and will I need those extensions? I've noticed other HFC use a J-bend anti-fouler setup. Looking to match something up with my F.I. cat back and noticed F.I. also uses a 300 cell metallic core HFC.
PM Replied!
