I'm just wondering if anyone is running a flo pro muffler on stacks. I like the sound of that muffler because it sounds like a quieter straight pipe and not real muffler with the straight through muffler. The stacks are just too loud. If anyone has a 4" muffler they want to sell let me know please. Thanks

I have a Flo Pro dual exhaust on my truck, and the muffler stinks, it has no fiberglass in it, so it sounds ricey. I had to put another muffler on before the Flo Pro, and now it sounds OK to me

hope this helps, I have heard that Magnaflow or MBRP make good mufflers that go well with stacks

 

My truck has the dual Flo-Pro and doesn't sound ricey, must be a 3rd gen problem.
