Muffler Impact on Engine Dyno Performance

The borla mufflers look like an effective and cost efficient option compared to industrial silencers typically found on engine dynos. However does anyone know if, or how much, the borla type collector mufflers impact performance (hp)?

Thanks in advance for your thoughts and advice.

Save your time and headaches; install industrial or hospital generator mufflers and be done with it.
