    I'd always check www.hyper-flow.com as one possible source.

    I can't recall anyone ever posting that they were able to get a cat thru an authorized F source for something less than an arm or a leg ;) (like 2X or 3X the Hyper-flow price, and it's not polished.)

    As an ex-dealer, I would recomend the Hyper-flows as well. They are a great product and we have installed them on 3 cars with no issues.

    My 355 had its 30K service this summer, plus replacement of manifolds and cats. I went with the Tubi manifolds and the Hyper-Flow cats and I could not be any happier. The sounds is great, and by leaving on the stock muffler, it is not too loud, except when you jump on it above 4,000 rpm or so, at which point is produces a wonderful scream. I could always add a Tubi muffler on later, but I like the combo I've got...here is a picture of the workmanship of the Hyper-Flow before installation:

    Hi Dave,

    I guess that your picture apply to the main CATs (the ceramic ones). Is it correct?

    Let's assume it's the case. I then guess that the two holes I can see are for the lemba sensor. Was it just a "plug & play" job to put the Hyper-Flow in place with the sensor? Or have you had to do anything special?

    Bye for now,
    Christophe.

    Yes on all counts. It was definitely a "plug and play" exercise, although I didn't do it myself, but had it performed at the shop during the rest of the 30K service and replacement of the manifolds. No special adjustments were necessary.

    My cat died the other day. I was thinking about putting in a Hyper flow too. Is there any downside (other than environmental) to just removing the cat all together?

    You may end up with your "check engine" light on all the time. Not good, since it will mask any other problem that would turn on the light...since it is already on.

    Here is another aftermarket cat:

    Why are you expecting the "Check engine" to light on? I can't see why since the Hyperflow is ready to accomodate the "standard" two lambda sensor (before and after the CAT).

    I am also in NJ.

    I am guessing that if you have a cat. you need to keep the cat. to pass inspection. (Don't ya just luv it!)

    I didn't have my air pump connected and the private garage doing the inspection would not even start the inspection until it was connected.

    His question was whether there was any downside to "removing the cat altogether"...not any downside to using an aftermarket cat.

    Hugh,

    You're right. Sorry about the confusion.
