After driving my Ultra for 1500 miles, and completing 1st service, went for some upgrades. Bike was basically stock when I started. So, I added Vance&Hines Slipons, a Vance&Hines FuelPak, and an H-D Screamin' Eagle Air Cleaner. Pretty good results, based upon my "Seat Of the Pants Meter". Got some more rumble, but not too loud.[sm=happy046.gif] Put only about 20 miles on the bike, but am quite satisfied. Bike seems to run smoother, though only more miles will prove this out. Those thinking about a similar upgrade should not shy away. Did the work myself, in about 3 hours. FP was very easy to set up. Pipes are exactly the look I was after. Not crazy about the stock AC cover, so may upgrade thatnext.

I donot have the decel poppingothers have mentioned, but I can definitely feel that I'd like just a bit more fuel during decel. Perhaps a call to V&H Tech Support willhelp.

 

I just bought a fuel pak for my 2007 FLHTCU, I already have a high flow, and SE touring slip on's. I WAS NOT experiencing any popping but I am going to put it on anyway.
