Just have a few quick questions for you guys. I want to get exhaust for my '03 2500HD but don't know what to get. It has awsome flowing exhaust as it is, just want something that sounds a bit cooler ! If I were to just replace the muffler what would you guys recomend? I remember someone saying that the Magnaflow muffler had alot of interior noise, is that problem fixed? And last what can i do to my truck to give it a bit more sack, with out spending alot of money. I would rather spend the money on the car...it's faster!!

 

Well Maganflows don't resonate too much...nothing like a Flowmaster. The straight shot internals make for less resonation (and more power!) from what I understand. Similar to Corsa, Borla, Dynomax, etc.

I'd do a dual in/dual out muffler (cheaper) or an X-pipe/H-pipe with two mufflers. Really depends on if you feel like spending the extra cash or not.

Are you looking for a direct bolt on or a custom cat back?

Also 1BadHD just ordered a set of The Other Guys headers for the 6.0 motor (I assume that is what you have) and they are supposed to add somewhere around 30HP. They are a direct boltup for the 3" headpipes of the 6.0.
