Muffler Impact on Engine Dyno Performance

jrstock · 02-06-2015, 11:03 PM

I am considering installing an engine dyno in a semi rural location where noise may be a concern. I am thinking about running a pair of collector mufflers on a SBC to reduce noise. I am looking at the borla mufflers that s/c dragsters typically run. Has anyone had any experience running these or other mufflers on a stock/ss car?

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.
