Mufflers and jets
Posted: Mon Apr 04, 2005 11:18 pm
I just tok over an '80 SD and am fixing this and that. The previous owner fiddled quite a bit with the carb jets, so I am looking at this. The mufflers are original types, but are essentially straight pipes; there are no major baffles, just a lot of little bumps inside. Is this the way they came? I like the sound but am suspicious it is not factory. If major baffles have been removed, it would throw the jetting off. So hey, folks, are your mufflers like this? If not, did you re-jet and how?
