There is no horsepower loss. Turbo's don't need backpressure, nimrod.

david, yes but the turbo only needs backpressure to be turned. Whatever happens after that doesnt matter. You can even remove the downpipe right after the turbo.. it will only make more power as there will be less restrictions.

Exhaust cutout on a turbo? The closer to the turbo wheel's outlet, the more power at ANY rpm range past boost threshold.
On a N/A engine? Good only for mid to high rpms or just to add noise. Will lose precious torque if opened early, 'cause it will will mess with scavenging, something turbocharged engines don't need to bother with.

didnt know there were so many mechanics on youtube

I am only going to say this once... engines do not need back pressure. Back pressure is the resistance of exhaust gasses through the exhaust system. The less resistance the better. One thing you want is negitive pressure behind each exhaust stroke on the engine to suck out all of the exhaust and help speed up incoming A/F as well as insure all spent exhaust is removed from the cylinder.
There wouldnt be any hp loss no matter if it is turbo NA.
