Flowmaster super 44s sounds great. I would personally use super 44 mufflers with resonator delete and exhaust cut out.

 

Got my Magnaflow cat back installed last week. it sounds sooo good standing behind it.

Gets really stout if you nail it.

Is very subtle rolling down the highway to the point where i can hear my failing front right tire going whump whump whump.

the way the lengths of pipe are used to make it sound like it has separate left and right banks is neat too.

i am 100% happy with the whole affair - just wondered where my head was when i didn't get the down pipe and converter minus the stupid u thing.

 

Super 40's and a reso delete... sounds like a tornado!
