Hey guys (and gals). I'm pretty new here to the forum. I've done alot of research on many things that have helped me a ton. Thanks to you all for that. My question is -- I'm wanting to put an new exh system on my 04 FX4 RCab and am thinking Roush is the brand I would like to go with. Is there a way I can put a Roush exh system and to true duals with it? Like the idea of having an exhaust that's not that loud. Oh, and can I dump it out the sides or is there really any benefit to that? Thanks for any help. Sould have some pics up soon. You guys rock!!
