Take it from me...replace resonator with high flow muffler..not a glass pack. The glass pack is cheap but it wont last. The high flow straight through muffler will reduce back pressure and last....and give you a nice throaty sound.
You may even wish to replace the rear muffler with a nice turbo muffler. I replaced mine today and combined with my high flow resonator...my car sounds great and has better response.
Good luck!
