Anyone with an after market exhaust in Washington DC area?

[telecam]

I am still in the market for an aftermarket exhaust that looks nice, sounds good but is not loud. It's really hard to get an idea from the multitude of YouTube demo clips I found, the same exhaust can sound very different from one clip to another so, I would actually love to listen to an actual NC700X with aftermarket exhaust. Anyone in the DC are with one? Right now I am hesitating between MIIV Suono, Delkevic Stubby and Yoshimura R-77.

Cheers,
