Just got a '75 Eldo. Conv. w/ 500 -stock single exhaust. Can anyone offer suggestions to convert to dual? I'd like to keep it under $600 & would do one muffler (Edelbrock, Turbo, Flowmaster, etc.) w/ two 2.5'' exits, or true dual w/ two mufflers depending on cost. A friend may do the work & "could" eliminate the catalytic converter -anything to change/alter in the emissions if that is gone? Thanks in advance.
When I do exhaust on my 76 DeVille I am going with a true dual setup. Cats are gonna get thrown in the trash. Still have not decided on mufflers. I don't want the car loud while cruising but I would like to hear to 500 while I have the go pedal mashed.
Anyone every put an H-pipe on these cars? Hopefully there is room.
MTS has a new product, which is a complete dual exhaust system for a 1971 to 1977 Eldorado (without provision for the converters, which I guess you are scrapping anyways). Estimated price is 400 USD - but right now, its a prototype and I have a picture in his catalog, it looks very good. Maybe give Al a call (262 740 1118)

Re: Dual Exhaust Conversion
My friend says he's getting a tubing bender... so I might be getting dual exhaust soon. I plan on 3" pipe, no gatopower (cats), and either one of those mufflers that you can switch between a muffler and a straight pipe, or just 2 cherry bombs (glasspacks).
Or I could just run two cherry bombs off the headers and see how that works out..
