I install a TAG ( Turbo Air Guide) and removed the muffler on my 02 3500 a couple of weeks ago. I can see better acceleration and lower EGTs a few degrees. I used the muffler eliminator from Geno's & the 1st generation TAG. John Holmes talked #@$%!about both of them at May Madeness they work. Oo. Harry
