Hi everyone, I'm relatively new to posting to the list, but I have been reading for awhile. Forgive me if this has been answered. My Dad's DMC has twin turbos on it, I'm not thinking they're stock, but they do have some sort of DMC logos on them. First question, Grady's on LI, just told my Dad they don't do work on cars with turbos on them anymore. Anyone else heard this? Second, anyone know where we can go for replacement mufflers? They two we got are totally shot. Exerpt from my dad's email: Rob Grady said he would not work on a D with turbos any more. I have tried the OEM muffler manufacture (Walker), also Borla and Flowmaster....no body makes a muffler that size i.e. 10" long, 8 ¼" wide (oval), 2 ¼" center inlet, 2" offset outlet...2 ¼" outlet would be ok....but 10" long is all it can be. If you have time, could go DMC online and ask if any one has found a replacement muffler for these original "Turbo Manifold" twin turbochargers? Thanks for any help you got! Aaron Townsley
