90 2nd Gen 4Runner Keeps Breaking Mufflers
Hey guys thinking of pulling the trigger on a 90 4runner with a 3.slo with a SAS running 35s lockered and geared
Seems like a pretty good deal it's from a friend. Says it has an exhaust issue as it keeps breaking mufflers, as in the factory weld in the mufflers, ummm any ideas?

If you beat the snot out of most anything you can manage to break anything.
I think this is a driving style problem all those hard landings trying to be the General Lee
Then if he is buying junk mufflers replacing them every two weeks.
If the muffler is breaking what else is braking .
Give them the benefit of the doubt Maybe they have the exhaust system mounted to ridged

It could be a fueling issue. hard to belive timing and no other symptoms. pull the plugs and read them. A dead cylinder would do it, provided the cat is gutted or removed. I've seen it in different vehicles where it will ignite unburnt fuel in the muffler and blow the end off. even bought a first Gen z24 that turned out to have a seized distributor advance. repaired the muffler since it looked good otherwise and less than a mile it blew out the muffler and I almost blew out my pants next to a cop, lol. if the cat is good, it would cook cherry red from the unburnt fuel. I cannot think of another reason a muffler would do that...... well, actually if the bump stops are gone you can bottom out on the exhaust pipe off roading.
