That’s what I was thinking, too. I imagine most of those folks don’t have a flow bench in their back yard.

As a result of their sponsorship of the NMCA/NSCA “Fastest Street Car” series I’ve had 4” Flowmasters on my Chevelle for about 20 years. No issues and they have that distinctive Flowmaster sound.

A lot of guys around here run them on their 6 and 7 second street cars. I imagine they would be too loud for daily use (for me, anyway).
