Hello gents! Just thought I would share my experiences with my exhaust system. First of all: I have a 1994 Nissan Pathfinder, SE, with VG30E. I installed PaceSetter headers roughly 6 months after I purchased the "Patty." Let me just say that Pace Setter headers are pathetic. In the design, they failed to account for a bolt that was protruding from the rear of the driver side head. I checked the system over and over before I actually realized that bolt was causing a gap/exhaust leak. What should have been a 2 hour job, ended up becoming a 2 week job that ended with me taking the vehicle to a shop to have it welded to account for incorrect design. In short, I don't like PaceSetter. After getting the headers to fit, my exhaust system experienced some other "changes" (oh to be young and stupid, again! ) The first system that I installed: True dual exhaust, high flo cats (I don't think they even were actual cats, to be honest), and Glass pack mufflers. The exhaust was cut off before the rear axle. This exhaust system was fun (what's more enjoyable than taking to the streets and being louder than rice burners!?), but good heavens it was loud. Around 4,000 RPMs, it would wrap out and would be louder than a semi's engine brakes (yes, I was one of 'those' guys). I took the O2 sensor off, and relied on the default intake and injection systems. This might come as a surprise, but I was pulled over for 'too loud of exhaust.' The second exhaust I installed consisted of the same piping, cats, just with Walker Quietflow mufflers. These were compliant with the sound restrictions, but they sounded like hell had broken open (and not in a good way). The third exhaust system I installed consisted of the original system: Y pipes to the cat, then back to muffler. I had to cut apart the old exhaust to take it out, originally; so welding was in place to put it back on. I felt a little frisky again, so I re-welded one Thrush Glasspack muffler in, instead of stock muffler. It was relitively simple job, but a pipe bending machine was needed. After I installed everything, it sounded mean, but it would cut out (it would almost die) when cold. I talked to quite a few people, and they all said different things - some said it was high restriction in the cat, some said that it was O2 sensor, some said something was malfunctioning in the engine, etc. I know this is a long read, so I will get down to the point. haha I replaced the O2 sensor, and it never had an issue, again. I had to reset the ECU to get the check engine light to go off (that was a relitively easy job). If you have trouble with your pathfinder dying (intermittent 'bogging down' and a rich burn), I would recommend looking at the O2 sensor. It can really screw with your fuel pulses and intake systems. I bought a new O2 sensor from o'reilly for $60, and it solved my issues. For you youngin's who are wanting that loud exhaust system, be sure that you do it right. It can cost you a lot of money and time later on down the road if you don't do it properly. You might also have to pay the local courts a few visits. My recommendation: don't attempt to tinker with exhaust without doing a LOT of research beforehand.

I would enjoy a disco ball in the back of my Pathy. I feel like it would really add to the ambiance.

Hello all, How do I view past topics? For instance: I am trying to view articles regarding 90-95 WD21 pathfinders. It says there are 4,620 topics; however, I can only view the topics (I assume) from this year. Am I doing something wrong?? Yes, I admit I'm a newb when it comes to this sort of things. Darn computers. Haha Thanks much! -Tag

Sorry for not looking at the some of the other threads. I searched for threads regarding hydrogen but couldn't find any results. I promise I wasn't trying to make a double post! I'm new to this forum, so it's taking some time to learn how everything works here. Thanks for bearing with me, though! The main reason I posted this thread was to see if there were any personal accounts of them working/not working. I've already done research about how they work, online - like I said, I came up with mixed theories. I think it's time to just wing it and see if they work. If they don't, no biggie. If they do, go me. Thanks again, gents. And like I said, I didn't intentionally double-post.

Well, I at least put one picture up. Sorry about the poor quality - gotta love cell phones. More to come! Thanks for the welcomes!

So what you all are saying is eat a bunch of beans and have an intake system right under my seat? Gotcha! I'll report back when victory is mine!

Hola friends! Has anyone read/heard anything regarding Hydrogen kits? I'm thinking of putting one in my Pathy to give it a little boost and help with fuel economy. I'm very skeptical about these because I've read mixed reviews. My instructor said he helped his friend install one, and his friend boasts 95mpg's on his little Accord. That seems a bit far-fetched to me, but oh well. From what I've read on the internet, they're not all that they're cracked up to be, but I'd like to hear if any of you have tried them on Pathfinders. Here's what my instructor recommended: http://www.hydrogen-generators-usa.com/hydrogen_car_kit.html From what I have found, they will work turbos and superchargers (I hope to eventually use a supercharger...). These sound a bit too good to be true. Thoughts?

...I've already learned more in the 2 days that I've spent on this forum than what I've learned in my class. I guess you win the bet?

My use has been a vehicle to get from point A to point B. My father and I love to work on cars, we just don't get a chance to use them a whole lot for 4wheeling. However, I really, really, really (enough really's?? Haha) would like to start going through more trails.

Thanks, gents! I've had my Pathy for about 2ish years now, so I think it's about time I start some mods. I'm fairly familiar with the components, and I learn more in each class (my instructor allows us to work on our personal vehicle at times)! I will try to upload a few photos. Thanks again! I'm really excited to finally be able to talk to other Pathfinder enthusiasts!

I'm not going to lie: I was super excited with my pathfinder! After just putting a 2" body lift in it, and replacing some wiring and horn assemblies; I was on top of the Pathy world. Then I looked here, and saw all these incredible rigs. Holy wow! Mine does not even compare to these beasts. You all are an inspiration to me and my baby Pathy. I can't wait to really start with the mods!
