Re: [Chrysler300] Big block mufflers

[Gary Nelson <garythepartsdoc@xxxxxxxxxxxx>]

I was informed at the Sema show by one of the major after market muffler 
mfg's, (including there's) that certain mufflers can not be put under the 
cabin of a vehicle due to the drone. The cabin of David's Suburban goes all 
the way to the rear.

I would consult the mfg., (not store or muffler shop) what would be the 
correct muffler for your application.
