    Default 1985 Fuel Injection

    I'm thinking of buying a 1985 lx with the first generation throttle body fuel injection system. The car needs a complete exhaust system. My question is, will headers and a real dual exhaust system confuse the old mass density computer?

    I wouldn't think the mass would care about the exhaust side.

    I thought 86 was the first year for EFI, 85 still had a CARB.

    Some 85's had a throttle body with two injectors. I'd still like to know if i can change the exhaust system without confusing the computer. Better breathing on the exhaust side should not affect vacuum, the variable in a speed density system, but not sure
