4" 304 exhaust 2007 Mega cab dually

[JoeLeonard]

I need help deciding which 4" 304 single exhaust cat back system will be the best and easiest to install. We have a 2007 Mega cab dually with the 5. 9 engine. I am considering MBRP and Volant, but the technical person I talked to at Volant said they are still months away from having one of their systems for the Mega cab available to purchase.



I would also like to know the best source to purchase the exhaust system from. Any help would be greatly appreciated.
