on my 96 5.9 i did a full magnaflow system with customs stainless pipes...true duals from the manifold, 2 hogh flow cats and magnaflow stinaless mufflers...AWESOME...it was loud though, but amazing. my friend has the truck now that i have a 2010 ram, but i sure miss the exhaust on the new one...if i had an extra grand laying around...id take the new out to get done too...just maybe not so aggressive until i hit the gas...
