What mufflers for 340

Sound wise, I believe a 40 series Flowmasters takes the cake
Something about Flowmasters is just pure muscle car sound.
The problem with Flowmasters, is they don't flow as well with their chambered design.

Best flow would be a straight through design, like a Magnaflow or Dynomax.

My next car, I will try out some Magnaflow mufflers.
