BB vs SB exhaust

[69coupe]

I am getting a 3inch exhaust made up from the collector flanges back for a Small Block. After rego :rolleyes: the Big Block goes in. Question is how far off are pipes between SB and BB :confused: for a first gen Camaro. The extractors for both engines are Hookers.
Length is not a problem its more the width for the X pipes.

i'm by no means an expert, but i would have to assume (because of the block width difference) they will not match up exactly.. but then again, how much difference can there be?

Depth should be the same though... if anything, get them to do it in sections.. so you can unbolt whatever doesn't line up and get new sections made to suite.

good idea. Will section the x pipe and just back from the flanges to the collectors
