A friend of mine on a track day removed clogged cat and jabbed the crap outta it with a long screwdriver, problem solved (of course if you don't have emissions tests).

Ont the SRT4 I personally watched there was zero difference in spool. The dyno chart looks the exact same. 1hp difference is so minor. I was freaking amazed!

Yes, modern Cats flow so well removing them is very hard to justify. To gut out a clocked cat or to save the cash of having to buy a new, I guess can be explained. But I personally, I think gutting a fully working cat to get a 1% improvement in power, as I have seen people do, is just unbelievably selfish.

Just my 0.02. *stepping of soap box*
