Which size ram pipes

Fitted the Maniflow twin HS2 inlet with refurbed carbs, nice braided fuel hoses, now the pancake air filters seem a bit tame!
Thinking of some ram pipes but not sure what size to go for.
I can get 1.5 inch or 3 inch.
Any advice greatly appreciated.
The engine is 1293, Piper cam,large valve head,Maniflow ex-manifold.

285 I think.
Forgot to say it also has one of Rich's HRG rocker covers which looks fantastic, I think ram pipes will compliment this!

Fit bigger carbs for starters.

The carbs have to stay at the moment but I think I will go for the 1.5 inch ram pipes.

Steve, running without air filters can wear the bores out in fairly short order if you're planning to use it

for road use I would take K&N filters with stub rampipes inside. This would be the best compromize for power and engine and does look not so bad.
