Cat + resonator removal

Hey, so I already have the muffler delete and am soon to redo my entire exhaust. I was thinking of removing the secondary cats and resonator while I'm at it. Anyone done this? Any gains? Sexy sounds?

Search that setup on Youtube. You should get a lot of videos with your setup you are looking for.

You probably don't know what your talking about.

Exhaust velocity is what youre dealing with. The size and flow of the exhaust determine the velocity, along with other factors... NOT backpressure...
Read up.

just wondering, if all the muffler, cats and resonator are removed, I assume it will impact the fuel efficiency or some sort?
