Which exhaust?

[atcoracing2123]

I was wondering what would be a better exhaust for my 2004 honda cr125r. Is pro circuit better for racing or fmf?

I would say Pro Ciruit.I have been running a Pro Circuit exhuast on my KX 60 and on my CR 125 and it has given me a lot of power gains where I needed it most.

Unless the stock one is trashed, you won't be happy with the increase / cost ratio. Louder? Yup. And that's a bad thing.
