1991 Toyota 22re pickup back pressure issue
My son's 1991 Toyota 22RE pickup with EGR delete kit with no cat. On stock Toyota exhaust with pins holes in the muffler truck runs good lots of power,but very loud. Removed and replaced muffler truck has no power when driving, even with gas pedal to the floor it will not go. Got it home and saw saw exhaust off, truck drive fine lots of power but very loud. Is the exhaust making to much backpressure or is there something else?

CAT plugged?
Exhaust bent in a way, or folded by someone trying to bend it in some way?

So strange.
Try taking off the battery for a bit, so the computer "relearns".
Mine did this once - brought it to a shop in 93 and they rebuilt the bottom end. I really doubt that was the problem, because your problem sounds just like it - seems exhaust related. It drove, but zero power. Give it gas and it makes a deeper sound but doens't move. Feels like 20hp.
Really interested in what others with say here.

Does the check engine light do anything?
Try to read the codes from it. No obd.
Oxygen sensor is installed and hooked up?

Packaging material crammed in muffler? Can you see through the muffler with a flashlight? Can you have someone blast compressed air in before the muffler while you feel for air flow at the exhaust tip? Welder used a flange that was significantly smaller diameter? How did you go about deleting the EGR?

No material in muffler,I was the welder just cut out old and welded in new, LCE EGR delete kit. No problem with old muffler and making power. Just after I installed new muffler.

Well if it’s good with old muffler bad with new I would say muff, BUT that’s oddly odd unless maybe something came loose inside while in production and caused blockage, but that’s just weird.....
