Can't decide what exhaust to get

NickD

So I'm looking at the FI, Ark and Motordyne exhaust systems now and I'm torn between FI and Motordyne.

From videos (since I havent seen any in person yet) I love the sound of the motordyne, but FI is claiming some serious gains just from an exhaust. Can anyone vouch for those numbers? Looks like 20-30 whp ???

These are the dyno results I found posted for FI:
