    "flowthrough" cats

    I found a link to these on SSS forum. I might get some, nice thing is cops around here don't crawl under and check and my town doesn't do emissions testing. I think their HP gain is a little crazy with up to 50! What do you guys think of these?

    I'd believe 5-10, but 50...no way.

    They are a great idea if there are visual inspections in your county...but a waste of $$$$ if not.
