I installed the Duff long tube headers and dual exhaust back in like '91?....can't remember shit anymore...anyway still going strong. I had Cherry Turbos originally. After about 25 years they were blown out, waaay blown out by then haha. Installed Flowmaster Delta 50's back in like '14 or so. They are great but almost too quiet, lol.
As an interesting note....back in '14 or '15 I installed Duff long arms. This would require their updated headers to clear their long arms. This would have added quite a few hundred bucks to my already expensive Duff long arm mod, ouchie.
But Monster Mike (Duff "Mascot" lol) heard of my financial woes regarding this next mod.....i was going to have to wait awhile to sequester a little more cash before pulling the trigger. He reached out to me and offered to sell me just the one side header that actually has to be replaced to fit the long arms. I was stunned.....
I said, "You will sell me just one header?" Mike said, "Sure I had some extra ones made for cool eb folks like you"....that was a few years ago and I got one of the last single headers he had.
So yea.....I'm a little biased....
Love me some Duffs.
You will too.
They got eb's figured out Hoss.
