Hello everyone I’m looking for a dual exhaust crossmember for a 76 cutlass supreme it currently has single exhaust can somebody help where can I find one that will fit so I can run the dual system thank you
also looking for a direct fit 2.5 dual exhaust anybody knows where I can find one they only sell for headers not for exhaust manifolds can anybody please help thank you

You need to find one from a '73-'74; '75 was the first year for catalytic convertors and the last for true duals.

FTFY

When they introduced the catalytic converter exhaust systems GM completely did away with true dual exhaust, even on the Corvette. They didn't start changing back to true dual systems until the mid 90's

Bouzouki

so the 74 crossmember will fit the 76??
also looking for a pair of #6 heads if anybody gas any and also a dual exhaust where can I find a direct fit thank you

I posted a parts wanted ad here for mine ,took a little while but did get one .Yes the 74 dual hump will bolt right in your 76 using your existing holes no drilling required

Bouzouki

Thank you brother

You can also use one from a '73/'74 Chevelle, Monte Carlo if that helps expand your search.

Cutlass, Chevelle, Monte Carlo, Skylark, Lemans.

crimsoncolby

Don't think Skylark will be wide enough. Century would work...as will Grand Prix, Grand Am, also. DO NOT use an El Camino/Sprint, though.

vintagepne

Check with Fusick Oldsmobile parts or YearOne I remember seeing what you are looking for at one of those companies.

svnt442

I couldn't remember if the skylark was an A body or X body those years. I looked it up and It appeared to be an A body....meh. There is also the Buick Special, but I don't know if they used that name before cats or not. A friend had a 76 special with a 231 in it. It was faster than my 75 Cutlass with a 260....that's not saying much.

crimsoncolby

There are some aftermarket ones being sold. Personally, I like the looks of the originals rather than the chopped, boxy look of the repros...but, they do the job. I've even seen people cut and weld their own from a single exhaust crossmember.

Is this car just a driver? I have one off a 76 that the guy welded for dual exhaust. It's not pretty, but I'll sell it cheap.

Bouzouki

How much bro???

A couple pics. It's not ever going to fail, that's for sure!

Off 76 Cutlass

Rock solid

Looks like a sturdy crossmember but looks more like a gbody crossmember .

Summerof84

Wouldn't a g body one be 2" narrower? This measured 52 1/2" and was on a 76 S at one time before being scrapped. That's all I know.

deadeyejedi

Yes the gbody crossmember is narrower , I suspect the guy who built that one just used a gbody crossmember and made it the appropriate width for a 76 . He more than likely would have had to redrill holes in the frame as well .definately creative .

Summerof84

You do realize the 75-77 ones are angled to clear the catalytic convertor just like the G body?

deadeyejedi

Yes I do I have one of each sitting in my garage both are originals and the 75-77 doesn’t have no where near the bend in it that the gbody one or the pic above has .either way if the one pictured above was in a 76 and the op wants to use it by all means use it .

brownbomber77

64-72 convertible will work, you just need to drill your own holes in the frame. I have one from a coupe and it's 54" wide. I installed it and drilled two new holes.
