Good afternoon gents. I'm closing in on a year of ownership of my 17 Mustang V6 daily driver. The car is fun to drive (300 hp), good on gas when I behave (87 octane) and decent in the snow (with dedicated snow tires). The trouble is I want a little more volume/sound without being too much. The Borla Stingers on my C5 are ridiculously loud with longtubes but I find that acceptable on a toy that I only drive for fun.
Has anyone tried Flowmaster resonator deletes on the 3.7?
Will they cause me any grief come emission time?
How do they sound (I've heard Flowmaster's sound clip)?
Or does anyone have any other options that aren't too loud?

Cheers
