    Rated 5 out of 5 by from Work perfect for my olds 350 I install the PYPES Downpipes on my 1970 Cutlass Supreme about a month ago . They fit perfect . My car/engine (350 small block olds) is all stock . The downpipes have 2 1/4 in flanges and the 350 exhaust manifold on the passenger side has a 2 1/4 in flange . And the driver side 350 exhaust manifold has 2 in flange . But it bolted up gust fine . I have read some reviews that said it did not bolt up to small block olds manifolds . But it worked for me no leaks fit great . If you did have a problem with the driver side manifolds 2 in flange you could gust grind down the flange on the downpipe a little bit . The downpipe flanges are really thick so you could remove enough material to get it to fit . I did not have to grind anything they fit . I have driven the car about a full tank of gas with no problems .
