If I were goin to run cut outs, that would be the best way as far as I`m concerned!
Summit has an exhaust kit like that-------- but my stuff is 3 1/2" all the way.
Clint< what was the plug hanging down on the side underneath??
Mine are Summit brand cutouts. The plug that was dangling is for the passenger side cutout. But since I moved them further forward, I have to re-route the wiring.
