I have 95s in mine, its honestly just preference of how you like your car. I hate cars that you cannot feel anything in, I like the rattles, bumps and noises, it helps you feel what the car is actually doing. The 60s should be just a bit stiffer then stocks which is completely fine and will reduce wheel hop significantly.
Are those just mufflers or a whole system? You wont get any "pops" with just a muffler if that is what you bought. You also wont have any rasp if the rest of your stock exhaust stays in place, the stock system is incredibly restrictive.
