I,m interested in putting your fatshots on my 07 ultra which is bone stock. Is there any difference in using my oem header pipe or true duals.And will this cause more or less heat? Will i get any performance improvement from slip ons?

Performance wise your better off with your OEM crossover and you can expect a 3-7% gain across your power band on a stock machine. The biggest argument for "True Duals" is the reduction of heat generated by the stock crossover, on the right side rear cylinder (passengers right leg).
