so everyone is running single mufflers? right now i have dual Flowmasters, 40 series i think, they were on the truck when i first bought it.
it's only 2.5" exhaust but for now i'm just going to tie my 3" headers back into it. eventually i plan on running 3" all the way & i'm not sure if i should stick with the 2 mufflers or go to 1 muffler.
