<VV> Muffler resonating

[bernievogler at comcast.net]

I have had several situations of resonance, but I think it can be corrected by turning the exhaust pulse away. I turned my exhaust down and out to point away from the car. I can't explain why it made a difference, but it worked. 

{I run 2" exhaust with headers on a 140 - 4 carb motor. I actually use Mustang V-8 mufflers - they are smaller and lighter and sound pretty good!} This has nothing to do with your Turbo system . . . but I do think that turning the exhaust will help. I prefer to the side, but down may work as well.
