This is wrong.
Supercharged engines like the 55 still rely on 'normal' exhaust physics which includes backpessure. going 'too big' WILL result in a loss of power especially in the low/mid range. there may be a slight increase at the higher rpm range, but the loss in the power curve would completely negate any negligible gain in the top end.
On turbocharged motors, the theory of no exhaust is true since turbochargers work off the pressure difference between inside the manifold/compressor and the exhaust.
stop spreading internet stupidity.
