    Thinking about upgrading the cats on the 355. Have done a lot of dd. There seems to be quite a bit of product out there, some of it marginal! Certainly from what I have been able to ascertain, the Hyper Flow cats manufactured in Georgia have received a high level of review. However, they are a little pricey, $2,300.00/pr. I have subsequently found an alternative in California, ProSpeed Prestige priced in at $1,695.00. I spoke with the owner/manufacturer last week. Very high quality person committed to a problem free product. Has anyone purchased a set from ProSpeed and able to offer comment. Quality, fitment.

    Thanks

    Hm

    Problem free cat converters on a 355 is a really big statement. Ask him what he would do for you if the new cats throw some CE code that reads low cat efficiency. More than half of the Hyflow ones do that.

    There is a inexpensive way to eliminate CEL by using spark plug extender ...so any choice is good major difference is CEL count

    I can't speak to Pro Speed but I can tell you that Troy at Hyperflow really stands behind his product and has put quite a bit of R&D into the product to build the best and most efficient cat he can.
