Well i will put it this way. If you do this you will get some droon. And if you decide that your gonna put some highflow mufflers in the rear it will droon/rasp like crazy. IMHO i would cut the rear mufflers off and put str8 pipes on there and finish it off with some nice tips. This way you will not get any droon or rasp. If you do decide your gonna cut your res take it with you and let me know, I know someone in the chicago section looking for the stock res.
