Finally completed this mod 2.5" piping and 2.5" DUAL TIPS!! I cut a hole in the LUNG looking resonator and added dual outs. It looks like a straight through design inside the resonator so I figured it would work. It sounds AWESOME!! No drone in the cab and its not too loud.
The sound is similar to deleting the lung resonator and one of the silencers BUT its a deep throaty sound!! Best part is I didn't have to buy any other mufflers. It REALLY does sound great.
Overall a great mod and project. Just measure twice or three times and start the cutting!!
I definitely have no regrets and would do it again in a heartbeat. I love the way my car looks and sounds!
