I'm thinking of deleting one of the rear mufflers on the 430 (MY04) for a little more burble, but not too loud and little to no drone.
I don't think i'll want it that way 100% of the time, so I'm thinking of a diverter that will block that exhaust when crusing which is 90% of my travel and opening it up if I want to give it some more throttle or simply want some more of that V8 rumble.

Has anyone done this (I'm sure it's been done) and what set up is best?
Simple rear muffler delete? Or is it best to divert from another point in the system? Pre-catalytic converter?

Any help appreciated as always

 

Some folks installed an e-cutout. Is this what you're looking for?

Yep, not as loud, but yes, the ability to have both louder and OE quiet would be nice.
Thanks!
