91 ls400 exhaust question

Recommended Posts

My car started running hot, everything checked out OK. I put my hand over the exhaust in the rear of the car and could barely feel anything. I ordered 2 new cats but when I removed the old ones they appeared to be fine. Could my 4 mufflers be the culprit or there looks like a resonator of some sort before the mufflers where all the pipes come together could be the issue

Hi

If the Mufflers were blocked it would severely restrict the power from the engine but it could also lead to overheating also.

Let us know what you find
