I have been through several exhaust systems on ERA 669. What I have found that works the best are the Mega Oval Mufflers from Stainless Specialities. They were very helpful and agreed to make me a set with an offset 2.5" inlet and a center 2.5"outlet. The mufflers measure 6.5" X 2.5" X 18" which fits between the rails perfectly with no modifications. I have fabricated headers and 2.5" over the axel pipes. All of it is ceramic coated in black which looks great and semi original. The mufflers sound great! Not too quiet, not too loud, Just a deep healthy tone.
