My custom 2.5" single exhaust was approx $250.
Dynomax Resonator $55 after rebate, Dynomax Muffler $20 after rebate, $80 mandrel bend piping from JCWhitney, $20 for 7' 2.5" pipe, $20 chrome tip and $40 labor at a local shop.
No rasp, little drone, pics coming. 3k rpms has a boomy sound, but 250 rpm + or - takes care of that.
FWIW, single 2.5" mandrel bend, flows approx. the same as 2.25" dual.
