I just replaced the exhaust on my 1998 Pathfinder. I live on Long Island (New York) so we have moisture problems and rust from corrosion caused by using salt on the roads during the winter. I went with a Walker exhaust from Rockauto.com and it cost about $250.00 after using a 5% off discount coupon. You can find the coupon code by doing a Google search (make sure it is not expired). I replaced the parts after the catalytic converters. It consisted of 2 intermediate pipes, the muffler and the resonator and 2 clamps, 3 gaskets 5 rubber mounts.
The biggest problem in doing it myself on the driveway was the corrosion on the nuts and studs. Because of the corrosion each of the nuts went from 17mm size down to about 15mm. I started spraying them with PB Blaster penetrating oil a few days before and wire brushed the nuts and stud threads. I found that I only was really removing the surface rust and not doing anything to the corrision between the nut and the stud threads. The only way that I was able to remove the nuts was to use HEAT and be sure to only use 6 point sockets. The nuts were in such bad shape that you do not get many chances to use a socket on them or they will end up rounded off. I found it best to heat them with MAPP gas (propane is just not hot enough and Oxy acetylene was out of my price range). I found that mine were so rusted that I had to heat them a minimum of 5 times and spray them down with PB Blaster after each heating before I put a socket to the nut for the first time. Then you need to try to first tighten the nut lightly ( yes -- try to tighten before loosening) and then loosen it lightly and then lubricate it again. The goal is to break the hold of the rust. Don't use full force or you will break the stud. If you don't get that slight movement you must go back to the heat. Once you get the movement you can begin to loosen and then tighten the nut. You must continue to spray the nut to wash away the rust particles from the stud threads. Don't try to remove the nut in only one operation. As you loosen and tighten and lubricate you will find each turn becomes easier. You will also need to get 2 clamps and 3 screws from the Nissan dealer to support the 2 intermediate pipes and attaches them to a metal plate. My bolts were also very rusted. The plate was rusted and i repainted it.
I was very surprised given the corrosion of the nuts that I was able to find good threads after the nuts came off. I started removing the nuts even before the Walker exhaust was delivered. I ordered 8 nuts from my Nissan dealer and 2 studs. I wanted extra nuts in case I had any problem with the old threads. I thought I was going to break at least one stud and be forced to drill it out . I used the 2 studs and 4 nuts to connect the muffler flange to the resonator flange. You could also use bolts. I also found a ground strap rusted away that connected the muffler to body and I replaced it. I did not replace the various heat shields that covered the original muffler parts because they just rusted away. Be sure you use anti-seize compound on the nuts and studs when you put on the new exhaust.

Anyone seen the new PF at a dealer yet? The pictures I've seen look great - much better than the Armada. Anxious to see it in person.

If you go to posts 7102 and 7013 you will be able to read my description and get a link to pictures. Also a couple of other people made some comments and suggestion about modifying the fenderwells. (By the way, my nickname on those posts is "nne3jxc" not "langod" -- but it is still me.)
As far as the mods -- this'll sound strange - but all I did was glue a couple of 2x8 "bump" Lego blocks inside the innerlip of the fender well between the fenderwell and the plastic splashguard/tub. This pushed the tub forward enoough to clear the tires. I also took off the mudflaps....
If you can't visualize it, go look at the pics...
PS: Sorry about the slow response -- I'm currently 600 miles from home....

jim243: I really appreciate your detailed info. While I'm fortunate to be in NC now, I spent about a decade in MN, so I'm well aware of the fun snow and salt create with exhaust systems. Other than the frozen nuts, sounds pretty straight forward.
xplorx4: thanks for the tire info. I'm not looking to get real big tires on my Pathfinder, but the selection in the stock 235/70R15 is pretty meek. Unfortunately, tire sizing isn't my strong point. Do you see any issues if I run 235/75R15s, other than about 1" bigger diameter? I'm hoping to get Goodrich All Terrains on there, or perhaps the Geolanders...

well, I got it out and then it came back on, P020 and 030, catalyst below acceptable level. Anyone have a cure. I am spent. I keep reseting it, after a week, it comes back, same code etc. Changed plugs, still comes back... Hope to hear from someone.

Got my invitation to view for the 27th in Edmonton.
I thought we were seeing "expensive" fuel and were trying to cut back on consumption to reduce CO2 emmisions. What's with 300+ HP Terrano's, 4 L Pathfinders with 270 HP, etc? I find it funny in a "caught in the headlights" kind of way.

Howdy. I drive a 2000 4x4 Pathfinder SE.
So yesterday I'm trying to troubleshoot the lights on my utility trailer, and manage to short across the contacts with a screwdriver. The Pathfinder is running at the time. A fuse(?) blows, which takes out my tail-lights and my dashboard lights.
Where is this fuse??? I've checked the fuse-block under my dashboard, and also the two blocks under the hood. Nothing is labled "tail lights" or anything remotely similar.
Can you point me towards the fuse/link/relay that will turn my dash-lights and tail-lights back on???
