^ +1. I prefer the sound of an H pipe too.

Not the loudest, but I bought the GT 500 Ford Racing axle-backs from American Muscle, and they sound perfect. Nice idle rumble, loud when you get on it. Painted them black so they hide better.

They're pretty inexpensive too.

For a deeper tone and improved flow, check out a catted ProChamber mid-pipe. You can keep the FM 44's. Opinions aren't worth much, so check out alot of you tube videos and see if you agree.
I think you will.

ProChamber 5.0 Coyote Engine

I had a pro chamber on my car with cats for awhile. I honestly hated it. It was quieter than both the X and H pipes were with the same mufflers (so quiet at idle it sounded like the factory exhaust), and the drone with it was unbelievable. I then ran it without cats and it was just stupid loud. But that was just my experience. I've heard a few clips of S197's with pro chambers, and done right they do sound good.

It's almost impossible for 2 cars to have the same exhaust system. Different manufacturer cats, headers, size piping, location of components, ect.
I don't know anything different but I had Magnaflow mini hi-flow cats welded directly into the inlet of ProChamber. After market hi-flow cats should not muffle the exhaust tone so much that it sounds stock, not at all.
*Stock headers, hi-flow cats, ProChamber, keep FM 44's- Should sound pretty tight!


Good Luck! Have Fun With It!!

Mine had Magnaflow cats on it too, not that same kind but small ones.

It just seemed quiet to me...especially compared to the H or X pipe. I'm sure at full throttle it was loud but at idle and low rpm's it was very quiet.
