Daveyca55 No - the engine pipes are all the same for B20A, B, E, and F - there's an EGR version for all and a non-EGR version for all.
If it's new and you're willing to part with it, I'm interested. Where are you located, and how long is this thing?
(Some versions are only 4 feet long, other versions go all the way from the manifold to the muffler under the rear passengers' seat).
