I am dropping my FXDC in for it's 1000 mile tune and am having Vance and Hines slip on mufflers put on to give it a better sound. I am not putting on the Stage 1 air cleaner or tuning (due to $$$). I had two questions...
1. Will just the new exhaust increase my horsepower?
2. Can I put the air flow kit on and re-tune later?
Thanks
