Are the exhaust headers the same for all 990's?
But are the mufflers the same between ADV/SM/SMR/SMT ? (I know the SD muffer is unique/different than the SM/SMR/SMT/ADV)
Inquiring minds want to know, as there aren't many headers out there that list "SMT", but plenty for ADV/SM/SMR/Duke
Power, noise, mapping, price, and the ever popular : "More power or just noise?"

They're certainly the same for the SMR/SMT. The spacers for the can brackets might be different though. Check out the parts fiche. If its the same number its the same part.
