Catted Y pipe for BBK Headers?
Outside of chopping up a y pipe and welding cats in, is there a catted y pipe that would fit nice with BBK's 1 3/4's headers?
I have a GMMG catback thats the only reason why i'm going with a catted y pipe instead of ory.

Yeah I drive a lot and don't want this thing insanely loud and unbearable. I've driven an F body before with GMMG no cats and it was like NASCAR at all RPM's, lol. Sounded like **** to me at the time.
Cam, manifolds, cats, and GMMG sounds perfect to me right now, but those extra ponies are desired.

I wouldn't go with one cat - too restrictive. I'd hack the BBK Y and install two. And then a bullet muffler or powerstick in the I.

I tried ORY with my GMMG and you said it - insanely loud and unbearable. Horrible rasp. I went to a custom 2.5" catted Y and that wasn't enough. It took a powerstick in the I and resonator tips to get it toned down.

Everyone bows to the GMMG, and don't get me wrong I love it the way it sits right now...BUT it sounds like **** if not properly set up.
I think I'll follow your advice on this and go with two of those magnaflow cats along with the powerstick.
