The Ark as far as im aware is on the quieter side, but it can get loud when you step on it. I like it because it has no drone and it sounds great, nothing obnoxiously loud but a nice deep note
Regardless of which exhaust you choose, your going to love it but for what its worth If you can spend the extra bit, i'd say its worth getting the exhaust you really want.
Search deep for a used one or find out if they go on sale on holidays. Money comes and goes, we sometimes forget that we need to live for now not just saving for later. Assuming its not going to financially cripple you, i'd say go for it.
