Well the TTI muffs on the old Hemi are driving me nuts with a severe drone. So it's time to make a change. I'm thinking of Dynomax ultra flows or Magnaflows. Does any one have the Summit part number for the right fit dynomax for a 68 b body.Yes I think I have 2.5 side intake and 2.5 center exhaust. The case seems to be about 19 inches long oval shaped.

I am looking for some releif for the drone along with some performance increase. I am not looking for an ultra loud muff. I know this has been discussed many times but your opinion would be welcomed.
