My '95 Vulcan/AX4N was running rich due to some changes I made to the throttle body (since fixed), but I fear it already killed my passenger bank cat. I don't much care about its functionality (FL has no emissions testing), but now i've got a bunch of rocks rattling around inside the thing. I'd take it to a muffler shop, but I presume that they won't just gut it for me (still illegal, right?), and I don't want to pay money I don't have for new cats I don't want, just to get rid of the rattling.

I looked at the possibility of removing the downpipe assembly (FL car has seen no salt), but I'm not sure exactly how I'd go about gutting the thing afterwards...

Or, I could cut the cats out entirely and replace with straight pipe, but I don't have welding capabilities, is it safe just to clamp a length of pipe in there?

No matter what I do, I know I need to do it to both cats, since I don't want unequal back-pressure on my cylinder banks...

If anyone has any experience in general, I'd appreciate any tips or advice on the matter.

One of the cheap ways out would be to get a junkyard cat and have some shop weld it in. I doubt that clamps would hold; the Taurus exhaust is stainless steel, IIRC. (Stainless has a large co-efficient of expansion.)
