Why not remove the cats? and high flow cats are dyno proven to show no or little results compared to stock cats. why waste of money

I have a 2006 4.6l, and did the cat deleat, added the O2 simulators, added a Flowmaster SISO with a 4" stainless tip. WOW is this mother loud
Obnoxious just like me!LOL. Actually felt a bit more torque and revs higher to. The worst part of removing the cats for me is the fumes I get now that the cats aren't removing them.

A Curve Ball?
Been reading all about the exhaust issues and now I feel a need to let ya'll know what sort of mess is under my 96. The guy I bought it from last month said he had a "new" cat installed. No issue there but just a wee bit closer the engine is the suspected problem. Between the stock piping at the engine and the cat is a 4" section of pipe going into a 3" inlet to the cat and on to the Flowmaster with dual outlets. I believe I am losing all kinds of low end torque but it also feels like the high end is also suffering. I'm not a exhaust scientist or anything, but, this just doesn't look right.
