I'm running true dauls 2.5" with an x pipe and empty turbo pack housings, I had it at about 2800rpm at the redlight warming it up alittle during the last cold snap(around 25*)we had and didnt notice the deputy on my bumper for a few seconds,but I let off of it and granny shifted it when the light went green no blue lights. :sweat: I like the sound of twisters if youve gotta have mufflers, the thrush magnum glasspacks sound good but are disappointingly quiet.
