BLACK DORIS 9 Report post Posted January 20, 2017 Hi all, current og parts are in need of replacing. Muffler is the most problematic but wanting to do exhaust at the same time. Not looking for any drastic change in note or volume as the stock tone was fine by me. Numerous online fodder but hoping to find more user experience references/suggestions. Are second-hand systems worth looking at (considering age etc) and would any e30 exhaust and muffler unit fit or would model and engine need to be matched. Thanks in adv.
