Just a brain fart. How about leave your exhaust as is, from cat forward. Get a new larger DP installed with an electric bypass plate before the cat. I had that on a the DSM I bought as a donor car. The laser had stock exhaust with the exception of a 2.5" DP with the BYPASS valve before the cat. Is there a way you can go that route without getting your peePee slapped?
Press a button and you're wide open exhaust, when you're done having fun, close it back up to a quiet sounding car.
I did that before in another car. Found out that’s a sure way to murder your cat. Cats work by becoming hot. Opening a cut out before it makes what still goes to the cat become unburnt gases on the element and it becomes clogged or otherwise useless as they burn off on the elsement insufficiency and no longer sufficiently reduce emissions. Causing you to fail an emissions test before knowing it’s bad.
