Got some details? Looks like the "Pinebox Screamer" I've seen made for the 03-04 636.

Looks real good.

its a one off pipe, made by a local company here in brisbane, they even went to the trouble of setting it up on the dyno...dont stand close when its running, your ears may bleed and mind your kids it can eat a whole one

damn, my ears are still hurting by just lookin at it.

If/when I get an I4 liter, I have no probs with the back pressure decrease since those bikes have so much power, whats 140hp compared to 115hp? Still fast enough for me.

Backpressure is never a good thing.
Powerband tuning from an exhaust is the art of exhaust pulse scavenging and gas velocity.
The only reason a bike will run bad because of less backpressure is because the fueling has not compensated for it.
