Mufflers

Problem is the front crossmember for the ladder bars is right in front of the floor pan where it raises up where your mufflers would be. I don't see anyway to run exhaust pipe past the crossmember so my exhaust system is only going to be about 3 feet long. I want to fit a x-pipe in there somewhere. Are the bullet style mufflers louder than the flowmasters? I see that dynomax, flowmaster, and borla make the bullet style but haven't heard them. I'll have to check out the moroso's. Didn't know they made any.
