what mufflers do yall recommend, as of right now i have the flowmasters 40 series i believe, and their driving me crazy, so much interior resonance it's impossible to have a conversation inside the truck. plus the sound isn't that good either and i haven't even installed the lts yet,

 

Magnaflow
Corsa
Borla
not necessarily in that order.

 

You better add a hooker to that list..

 

and hooker

 

good job

 

Classic Chambered Power Sticks.

 

The Corsa sport muffler will be loud with headers and/or no cats. There are two Aerochamber mufflers, I assume the maximum flow version will be louder than the standard.
