exhaust system interchange from shortbed to blazer.
 

I found a exhaust system slightly used from a 67-72 short bed truck.was curious if I could could use it on my 72 blazer.

If it's 4wd to 4wd, I don't see why not. You might need to shorten it a little bit before it goes over the rear axle, since the wheelbase is shorter.

I have no idea if 2wd to 4wd or vice versa would be as simple. I suspect if they followed the factory routing it would be no big deal.

I would think the 2WD would more likely fit the 4WD than the other way around. Exhaust for a trailing arm 2WD Blazer is tricky but I don't see where it would be different than a 2WD short bed. Now trying to do what I want to do, which is a 3" side exit before the wheel and be above the frame rail the whole way, yep pretty tricky. Luckily with my inline I'll only have to do one side.
