Exhaust pipe identification help - C2 maybe

[Ron L.]

Identification help needed for these exhaust pipes. They are 2" - approximately 58" long, and one side of each pipe is slightly indented for about 30". I purchased a 64 convertible, and these were extra parts thrown in. Restoration efforts have revealed that the car was damaged on the front right side - whomever did this and some other radical alterations in the late 60's put a big block radiator behind a 327. Car came out of southern CA, and my seller purchased it upon release from the NAVY in about 1970. Thanks for any help.

The look like exhaust pipes applicable to 1964-65 Corvettes with 250 hp with manual trans or P/G or 300 hp with P/G, probably GM #3846533 and 3846534

Ron,

see Joe Lucia's post #4 below - I misread my source and don't want my incorrect information presented going forward w/ out acknowledging my mistake...
I have deleted the incorrect information...

Ron,

dunno if this is the case for '64s or not, but all small block cars in 1967 were 2" diameter - and all big block cars were 2 1/2" diameter.

For 1963-65 Corvettes with 250 HP or 300 HP with Powerglide were equipped with 2" exhaust. All others were 2-1/2"

For 1966-67 all small block Corvettes except those equipped with Powerglide were equipped with 2-1/2" exhaust. However, 2-1/2" outlet exhaust manifolds ended with the 1965 model year for 300+ HP small blocks with manual transmission. So, 1966-67 with small block utilized forward exhaust pipes reduced in diameter at the manifold flange only to 2".

By the way, all 1968 Corvettes were equipped with 2-1/2" exhaust. All 1969 Corvettes, including L-88 and ZL-1, were equipped with 2" exhaust.
