Has anyone put dual exhaust on a 4.9 I6?If you have,what kind,did it improve anything and how did it sound? I plan on putting a single in dual out FM 50.

I put a FM 40 series on my old truck and it sounded really good. If I had it to do all over again, I would have gone with a Ravin from Midas. But I can personally attest to the sound of the FM, and it sounds really good.
