A lot depends on where you are located and what parts of the system need to be replaced. The best approach is to go to 2 or 3 exhaust specialists and get written quotes. Make sure they all agree on what needs to be done. It is very unlikely you need the WHOLE system replaced. I have a '96 Pathfinder with 64,000 miles & have not had to replace anything yet. Most likely you need the rear expansion box replaced.

I had to replace mine recently (a '96, similar to the '98), as it was falling apart all over. It cost about $800 CAN for the parts & labour. Apparently, the exhaust is welded and so needs to be completely replaced. The new exhaust (non-Nissan) is now modular and can be replaced on an as needed basis.


I have a '98 and replaced mine about 3 years ago, and had 3 quotes ranging from $600-$800 USD. It sucked, but according to Consumer Reports, the exhaust system is the Achilles heel for the Pathfinders around that year. I wish I would have sucked it up and gone with the stainless steel option they offered me (about $400 more) because here I am 3 years later and in need of another one...

Hi there! Ijust replaced my entire exhaust system on my 1998 pathfinder. It was a diy,and it took about an hour to do.My parts were ordered from .Order the parts that are already welded together.The rest is basically "bolt off-bolt on". Make sure that you also the gaskets. The price from them is usually about 1/3 the price of autozone or advance auto. Good luck!
