You can just let it idle for a little while then make sure it is in park
and block the wheels and climb under and do a visual on the exhaust
system. Look for smoke and black streaks. Just because the truck is
old doesn't mean much, it's how good the exhaust is that counts. Both
of my old Jeeps, one with 315K on it, have all new brakes and exhaust.
Also make sure the tail pipe exits out 'behind' the back wheel and out
past the body shell. Some folks get cheap and stick the exhaust out in
front of the rear wheel. This 'will' cause exhaust inside because the
stuff vortexes in the wheel well.
