I am not familiar with the FlowMaster Delta 50. I have a set of FlowMaster MagnaFlow mufflers on my 1962 C10.
It's a 327cid with a mild cam (CompCam XE268H), Factory 4BBL intake, and Factory Ramhorns. Holley Mdl 4165 (650cfm) for the carb. True dual pipes, no crossover and they exit the truck under the rear steps, just in front of the wheels.

Here's a short video a buddy of mine took of my truck on start up and as I drove away in 1st, then 2nd. I was not romping on it, but it has a good rumble to it.

1962 Chevy C10 start up and drive off.

I have been pleased with the sound both under normal conditions and on the freeway.


They sure beat the GlassPacks I had on my old '63 C10 back in the day. :-)
