I hadn't thought of a custom... Is it the same price range?
I don't know about going catless as much as I'd love to, it's just a pain for me to have to put them back on for the MOT.
I don't want a particularly loud obnoxious exhaust, but something with a nice burble at idle, but has a decent soundtrack when on full chat.
Will have a look at powerflow for options.
The question will then be, which HFCs will work best with powerflow?
