    Hi Guys,

    I own a 96 F355 M5.2, with Tubi exhaust, thinking about swapping the original cats with sport cats. Any advise about whether I should go or Hyperflow or Fabspeed? What are the differences aside from price, is there different on sound or performance?

    If anyone have a used set I wouldn't mind an offer, or I can also order a new set.

    Many thanks,

    How strict (if any) are your smog inspections? Its tough in California so Fabspeed re-cored my original cats with the high performance cells inside. I get the stock look with the better performance. I've put about 400 miles on them so far and they seem to be working great.

    I am glad they are not the round tube cats that hit the motor mounts

    Offset is the only way to go

    Yes, except for the HJS German cat core that we import directly from HJS.

    Absolutely. We realized pretty early on that offset was the only way to go.
