Ok guys I had my new 3.5" in and out AES muffler installed
WOW what a difference ! No drone, can comfortably cruise in 4th gear doing 60km/h and it's quite, just a nice low note...
That raspy "tinny" idle sound has gone too
Very very happy, plus looks tuff as nails il post a pic up
AES make oval mufflers if that's your style
