What a timing, I just swapped factory H to X pipe and replacing current magnapacks for Borla xr1 race mufflers.

I had few popular combos.
Flowmaster axle back, factory H: I actually liked the sound but not for performance.
Ford Racing GTA, factory H: Just right. Really liked the sound and the mufflers are very light weight. Good performance.
Ford FR500S/KR, factory H: Loudest. Little heavier then GTA. Good performance or same as GTA.
Mid magnapacks, factory H, muffler delete: loud but sounded awesome part or full throttle. Good performance.
Mid magnapacks, ford racing X, muffler delete: quiet and mellow but screams at high rpm. Great performance.
Mid xr1s, ford racing X, muffler delete: TBD

Will update soon.
