I installed my Atom Bombs a while back and they are GREAT !!! You are NOT going to get a better bang for your buck anywhere.

BobVic is a great person to deal with. However communication is a teeny bit weak, takes about 3-4 days to reply to email, but he has a business so the delay can be pardoned. Since I'm in the winter wonderland I told him he could take as long as he wanted with my mufflers, and he did. But from what I've seen in other posts he does have a fairly quick 5-7 day turn-around if asked.

No flash/remap needed at all. And no other issues whatsoever. Simply install and ride !
