I don’t think you will get any more power with just a slip on exhaust.
you need to do a little more to increase power. Exhaust is mainly sound and optics.
there are many tests of different slip ons on different bikes and most of them even decrease power.

True. Then it might. Did not know.
it’s the same with the SC exhaust race set for my 800 RC. But also here, I do not have a Dyno.
i changed much more to get more power at low revs. Airbox, funnels and manifold.

A few bhp gain sounds about right for a slip on exhaust fitted to any modern bike. You need to remove the cat and fit aftermarket headers and remap to gain anything noticeable.

Most people fit a slip on for looks/noise/weight saving.

On my 1090RR I fit a full exhaust system, removed airbox snorkels, BMC air filter, custom remap. Saved about 8Kg in weight and gained 11bhp at the wheel and 4 pounds of torque. It did gain more torque at the lower end from 2 to 5k revs which made more of a difference to how it feels to ride.

same for me. Manifold, Corse exhaust, snorkels, funnels, MWR airfilter at my 800.
also around 10HP more at the wheel and complete removal of the torque loss between 4K and 6k rev.

unfortunatelly, I did not do a dyno before the modifications. The the comparison above is done vs. the measurement Of the MOTORRAD magacine.

Thicker manifold without cat has quite an effect.
