Just got back fro trip to DC- 1000+ miles in all -on our 2011 stock Tri-Glide. Bike performed OK but it is sluggish in the mountains 2-up and roasted us. So, after a year of reading the various excellent opinions on lowering the heat, what is the latest consensus? Planning on header pipe (any opinions on which?), Air intake, a race tuner....We like the sound of the stock mufflers. Can we do this ? Any latest whiz-bang solutions? The trip was great otherwise. Trike performed well and gave a good ride. Thanks for any input! ThumbUp
