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.

The car actually runs quicker at the track through the exhaust system than with open headers, Saves a lot of mucking around when I arrive at the track. Just put the slicks on and go. I do lots of highway miles and barely hear the exhaust noise at all, just the nice deep burble all Mopars have. 451" w/ 6 pack. 7229038-100_7699.JPG (152 downloads) 68 Charger 451 / 518 65 Cuda 273 / 833 04 Cummins 2500 2WD 02 Grand Caravan

Of course this is with a hi compression 478 Hemi. I would like a little more exhaust flow (which seems to be available with the ultra flows)but I do not want a total race muffler sound on the street when crusing. I was hoping some of the pure stock racers (A-12 guys ect. ect.) would chime in with their experiences and a correct part number for the right fit.
