    Does anyone have an idea of actual number of horses gained on the 1200 engine when stock mufflers and a/c are replaced (maybe some Rinehart slip-ons and a SE stage1 kit)?

    would have to recommend the rinehart slip-ons and se stage one. Did that set up on mine, never had it dynoed, but I could really notice the power increase and the sound is fabulous. Took away a little gas mileage, but I did not get it for gas mileage. I am sure you will be pleased with the results.

    FWIW, this is the dyno sheet from my '07 883 XL. I didn't do a baseline, but I've read bone stockers put out 44/45 hp at the wheel.

    This dyno was done after install of Cycle Shack slip-on mufflers, V&H FuelPak and the SE air cleaner.
