I had my resonator removed, replaced with straight pipe. Sounded awesome at idle, rev it and people would move outta the way. But, driving up hills & such it would drone like mad. A constant deep bass drone that got to be too much.
So I contacted Stazi the Auzie (CEG'r) and he set me up with a magnflow resonator. Sounds great, you can hear it on the highway. The idle is much quieter but still deeper than stock.
I've never heard a glass pack in the resonator spot. Is it a staight tube, only slightly larger than what was cut out??
About the rattle Aioutour, Buzzes at high RPM's in neutral? Or does it do it at highway speeds? Is it a loose clanging rattle??
