yeh just take it to an exhaust dealer and they can make it to your exact spec, you can make it as quiet as standard, but it'll still give you that slight increase in power and will look good......if you want it shown obviously.
I just pm'd you max and noticed your other post about the headlights. i suppose the slight corrosion could be fixed by getting it re-chromed, dont ask me how much this would cost, i have no idea watsoever. couldnt imagine it costing much due to it bein such a small area.
