Yep, sure have... I have been thinking about doing that on my truck. I
just thought it was interesting that Buick included a quick way to drop a
cat. I have been thinking about cutting my cat off then running two
y-pipes with a bypass around the cat and then installing a dump valve at
the front with a remote in the cab. That way I could have an "on road" and
"off road setting at will and if I place the bypass slightly inside and
above the cat the only way you could see it is if you are directly under
the truck.

When I get the chance I'll do it and photo doc it for the other members.
