Does anyone know if a 76 front Y pipe with out A,I.R. will fit a 75?

Some of the vendors list them as two different pipes...

It appears there are different size pipes (2 1/2" or 2 1/4") and a different flange for the catalytic converter.

You might want to call one of them and ask.

Take a look here at corvette central for 75-76 w/o a.i.r. (except california ... I think...it's cutoff).
The system:

The no a.i.r. front y pipe:

and here is the one with a.i.r.:

I mention corvette central because last year I went back to Ramhorns and installed the 2.5" stock exhaust system (well just about, I installed 64-65 2.5" front pipes) all the way back including the mufflers and it fit like a dream.

You will note in the description that part number "323740 1975-1979 All Front Y-Pipe (2Piece"...... Anyway, if you give them a call, and the fit of mine is typical, then they should probably know.
