I've got right around 10.5K miles on my Z (bought it second hand) and have my first performance mod on the way: Stillen HFC. The cats are new and have never been installed on a car.
My question is this: Should I order a new set of gaskets for installing the Stillen HFCs or will it be ok to use the ones that already have some miles on them? I found
these gaskets Berk makes and I assume they would fit just fine with the stock headers and Stillen cats. The question is should I be worried about the integrity of the stock gaskets after so many miles?
