Exhaust for 2003 Elise?

[DanHCT]

Can anyone recommend an exhaust for an Elise. I have a 2003 K engine all standard. We do not have yearly MOT in SA so cat can go! Must not be too noisey, just a bit more character and a little power would be great until funds allow engine swap.
Saw Brooke Kensington have a system for GBP 295. Anyone tried one? Recommendations appreciated, and if I can order online even better. Thanks
