Hi All,

Long time lurker and infrequent poster. I have an 89 rrc I've been working on getting running. The exhaust on it has plugged cats and all the joints are welded together.

I would like to ditch the whole thing and bolt in a new factory version. The exhaust set-up looks very similar to the one on my 91 but I am not 100% sure they are compatible.

Does anyone know if the y-pipe with cats from a 91 swb would fit an 89 swb with the separate cats?

Thanks!

I'd say compare part numbers but the only Y pipes with cats I have found recently are LWB. I would take some basic measurements on spread and over all length. Manifold spread should be right on since all NAS Classic, Discos and Defenders use the same exhaust manifolds on the same basic block. If you are within about 1/2" in over all length you should be good to go.

Thank you. I will take some measurements this weekend.
