I'm taking my 2011 5.0 up to the local shop to have my 19" borla pro muffler si/do and dual wall tips put on. should I have them take off the factory resonstor? I don't want allot of annoying drone. but I like a loud exhaust.

 

sometimes loud exhaust comes with drone. Keep the resonator on, and if its not loud enough, then remove it.

 

Sounds like a plan.

 

x2!

 

right on can't wait to hear it.

 

I agree. Try it with it on, and take it off later if you want more!
