SL500 R230 (2003) Exhaust Upgrade

[W111AAM]

Looking to improve the sound of my 2003 SL500 (R230). However, I don't seem to be able to find anyone that offer aftermarket exhaust systems for this model. Does anyone know of anyone or can point me in the right direction please?

Most seem to go for a resonator delete

rather than an exhaust swap.
