Okay. I picked up a new 1" Bi Metal Hole Saw and 12" Extension from Home Depot. Placed inside the 1" opening on each tail pipe until I felt it hit the Baffle Plate, it was a snug fit. A few minutes later they were drilled through. Just like the Exhaust Mod I did on my V Star 950. It added more volume and a deeper tone. For my liking, it is just enough without being too loud. It's enough to let the Cagers know you are near. I thought of buying the Cobra Slip On, but not anymore. I'm very pleased with the 4 half inch holes on the outer edge and the baffle plate drilled out. I recommend this mod for those who can't or do not want to drop big bucks on better sounding pipes. ;D
