brixton crossfire 125 xs exhaust choice without losing low-end pull

brixton crossfire 125 xs exhaust forum question

A rider asked about a brixton crossfire 125 xs exhaust because the stock sound is quiet. I want a deeper tone, but not a bike that runs worse or becomes illegal.

I found this related page while comparing notes: brixton crossfire 125 xs exhaust. I wanted a practical thread before guessing.

Would you check approval markings, DB killer, header gasket, oxygen sensor if fitted, plug color, fuel range, heat near plastics, bracket alignment, warranty, noise limits and baseline GPS speed first?
