New exhaust doesn't sound all that great

I've got a similar engine with a bit less cam, I have dougs headers going into 2.5 inch exhaust to 2 flowmaster 40s, and out to the rear. I love the way it sounds! Personally I've never really liked the magnaflow sound, but that's just me.

Get dual mufflers and bring the pipes out the rear or side, should sound alot better that way.
