MOPED ARMY

I agree with the circuit pipe for your trike. You dont want to hit the speeds on the trike that your pipe would start flattening out at. But will be really nice on that low end for ya. Or maybe modify one of your existing pipes to a side bleed.

I have a proma circuit on my garelli polini and it is great. Just tops out right around 40 with my current gearing. (edited)
