HT4100 4.1, 4.5, 4.9 Discussion, Is the exhaust layout identical per the 1983 and 1984 DeVille 4.1 V8 in Cadillac Engine Technical Discussion; Mainly in the exhaust manifold flange -> downpipe -> cat region.
Thanks in advance,

Do you know if the crossover pipe and pass. side downpip flanges are anything special where it meets the manifold. I'm thinking I want the muffler shop to just use the 3" Stainless I had them order for these pipes; Unless the flanges are a problem.
