Hey Terry, I think you'd run into some jetting/carb tuning no matter what. How about 2 into ones with two of their quiet core mufflers. I'm really pleased with mine, and the backpressure is substantial.
What 2 into 1 system did you use and where did you get it. I have some that came with the bike but are showing there age and I don't see any markings on them. They sound good to me and they turn out at the end.
Jardine made some cool 2 into 1's. might have the mfr stamp on a mount bracket @ the rear footrest.
