I have a decatted head pipe with V&H fishtail slip ons with an S&S stealth air cleaner. Originally I went with XIED's. This set up worked OK. I switched the XIED's out with a micro tuner from Fuel Moto and couldn't be happier with the results.
I certainly do enjoy not having all the heat from the cat.

Thanks guys for the input, I am running the xieds, tried that first. It seems to run good although hot. We went to la crosse wi last weekend, got caught in rain an 55 degrees. I still had my right leg on the highway peg at times to cool down. My 07 street glide I did 2:1 exhaust AC & power commander and Dyno tune. It ran great. On this bike, road glide ultra, I just want a cooler ride. The 103 is plenty for me at this time. I want to put my money in the gas tank . Thanks again
