What is the quietest 4" exhaust out there? I want NO cab drone whatsoever. The Walker BTM has been pretty quiet on my other rigs.

Also, will "freeflowing" the stock exhaust with a Walker BTM and some "gutting" upfront lower egts much?

I just want a basic QUIET Exhaust....

Something to consider is to take an aftermarket 4" kit and add a 4" wide open glass pack muffler up front near the cat to act as a resinator. I did this on my 5" kit on my current truck and it really quieted it down without inhibiting flow. I would imagine with the 4" system and the baffles facing against the flow on the resinator muffler, it would be pretty quiet.
