I know this is probably an old one but reading older threads and googling's just got me more confused...so the question is this

I have a RK 2011 (103 engine)...thinking of putting the SE heavy breather + SE pipes + XiED 10...how much performance (bhp, torque) improvement can I expect?

No dyno + tuners in India so lets not even go there...

 

You'll feel it, no need to worry about numbers, becuase you cant dyno it anyway

 

It will definitely feel more powerful. Usually about a 10% increase in hp and tq.

 

You can check out your two XiED options HERE.

 

Do you get good quality premium fuel in your area?
For some reason, I'm thinking "Double Hump" brands are common there...

 

Well worth the investment.
