How else can I improve the sound?

So as I said before my 115 came with the Scorpion exhaust and I plan on getting the Z&F remap later in the year. I don't want to decat as I'm not confident taking it off putting it back on for MOTs.



How else can I improve the sound? Not that I am unhappy with how it sounds currently, but I'd love a little more.



Thanks :)
