4" single muffler?

[ZACH'S97]

I'm going to throw a 4" muffler on my currently open 4" down pipe off of my pt88 4v set up. So far I've been looking at magnaflow and dynomax race mufflers. Anyone running a set up like this on a big single 4v? Lots of LS cars like this but I'd like to hear a turbo cobra with a large single exhaust. I love the open down pipe but need a muffler for some classes.

I have a 12" dynomax bullet in mine. Sounds good. It really mellows out the idle. At full tilt, it didn't change much. But, My exhaust exits the driver side bumper.
