Jardines were nice on my old 1200, sounded a little louder than stock, not loud but mellow. My 1500 has stock pipes and they are a weel bit quieter than I'd choose but they are in good shape so they will stay.
I am also looking at replacing the exhaust on my 83 GL1100 but have not made a decision yet. I have found out one interesting item about the MAC exhaust. You see in many of the advertisments for MAC exhaust that they are 18 pounds lighter than a stock system. It is more like ounces NOT pounds. It does appear to be a good exhaust however. Can anybody confirm MAC quality or longevity? Dean
