Message: [QUOTE="mikem, post: 1179796, member: 20037"] nice Cummins conversion, I'm jealous! i used to work for Cummins, machining and building motifs at the ReCon plant fortunately my SD came with no cat I'm definitely doing a bigger downpipe. just picked up a 3.5" magnaflow for a good deal, so i guess I'll give that a try since i already have a BTM and my stock exhaust is in good shape What I was really wondering is if there's any EGT advantage to 4" over 3.5" once you get have done away with the stick restrictive muffler and downpipe. I know it won't provide any power advantage at the state of turn I'm looking at. no info to be found on that specifically, just 4" vs stock downpipe i guess I'll find it soon enough if EGTs are an issue. I already have a 6.0 IC and will gut my EBP butterfly when I install the downpipe. does anybody think wrapping downpipe is beneficial all, or just a waste of time and money? [/QUOTE]
