Ok, I want the prochamber sound to go with my flows, any way what I'm wondering is if I weld on the stock cats, do I still need MILs? I honestly have no clue about these emissions systems, my 67 stang had a golf tee plugging the Cali Emissions system after I moved to NV so I know that golf tees wont cut it here.
Where do the MILs plug in, and how bad will welded on stock cats affect me? I know some of you will say if I'm welding in I should buy high flows... but why should I pay for something I'm about to throw away when I can re-use it instead?

You won't need MIL's if you put the cats in. THey plug in-line with the harness that goes to the rear sensors. The factory cats are not performance oriented,meaning they are small diameter and the construction of them is more restrictive than high-flow ones.

Just remember that the stock cats are for a 2 1/4 inch exhaust sytem. The Pro Chamber uses 2 1/2 inch diameter pipe.

No, that's not correct. They plug into the pipe, but without cats to absorb the unburned fuel and other crap, it will trash any attempt to pass emissions and will throw codes/kick off your SES light.

i don't think catted proChamber is out yet. This topic came up few weeks ago. I would like to get one when it come out tho. Send PM to Mike Raburn from Pro3i(his name here is "MRaburn"), and he can give you more info about it. But if I remeber right, he was the one that said its not available yet.
