Well in that case.. get the dual outlet ones than.. hee hee
. Yes the resonator is behind the cat. If you're worried about cabin noise, the wife complaining, and the kids all staring when you come pick them up
( thinkin you're Mad Max ) then I would leave the resonator in.. The new muffler will make it louder.. but the resonator will keep it minimal inside the car and out.. but you will still notice the sound from the new muffler.. if they're replacin it.. make sure it'* Mandrel bent pipe then and worry bout the Cat later.. ask if they can put that in without having it written up on the work order since it'* not OEM.
