RE: SPO mufflers

Late fall I put a set of V&H TD's and the SPO's on. Previously had stock headers and SE II Slash cut.A old dyno run netted 71hp and 86 ftlb.Also it's 88in with SE AF and 203 cams.I did play a little with the pc III and the accelerator pump function. My seat of the pants dyno feels no loss in low end, but no gain. From 2500 up to redline it is much smoother and pulls stronger. Seems like the sweet spot for cruising when up from 65 to 72-4. Mileage - no noticable change. There is a deeper and definite rumble from the true duals and spo's. No sharp crackle and cruise is much more ear pleasing. I put my vote for them.
