Anyone know the dimensions of the main muffler off hand? I'm at work right now, and about to order some parts. I think there are enough holes throughout my entire exhaust system to warrant a complete overhaul. I'm thinking of doing this (thanks to the everyone's input): 1. On each side, cut off the resonators (after the o2 sensor obviously) and weld SS straight pipe. 2. Weld the above pipes to custom pipes that go into a Magnaflow muffler- main muffler replacement. 3. From there, a 2.5 pipe that will run to the end. Either that, or main muffler to a new post muffler. I would definitely enjoy a nice tone, I just don't want it to be too loud. Hopefully all of this will be Stainless Steel or at least Aluminized Steel. What does everyone use for their main muffler replacement? Straight pipe through that as well, or Magnaflow? Or something else... Where can I get a Magnaflow muffler to replace my main muffler? I mean, I know where I can GET it- I need to know where specifically so I know what worked, what did not. Thanks in advance, Vannak

This isn't directed to anyone specific, but I don't understand why everyone is so quick to say that "No Back pressure is the way you want to go...". That's completely false. I mean, granted, there are circumstances where a larger diameter would be beneficial. But saying "The bigger, the better" without knowing about the application, is extremely wrong. Nissan ENGINEERS designed these cars, not you, not I, not the guy that is telling you to go 5" pipe all the way down. I agree that OEM isn't always the best, but if you do stray from OEM specs (while doing incorrectly), best believe you will encounter an SEL at some point. If you compensate for you upgrade appropriately, then cool, you're car will probably run great. I just wanted to get my .02 cents in there, not that anyone gives a damn...lol. The rust has taken over my exhaust, and I'm dealing with a few holes. I'm looking for stainless steel, or something comparable. I did have a quick question though, as I am a little new to the Pathfinder world: What Magnaflow exhaust is everyone talking about? Is it just the cats? Or piping? I've searched for a Magnaflow for the Pathy on their site, and there is nothing. Maybe you guys are talking about a universal muffler that you have to mod to fit our cars? Are you guys purchasing the exhaust for the Xterra and/or Titan and modding it? If someone could help me out, I appreciate it very much. Thanks everyone, Vannak

Ok, so I just replaced the idler pulley, alt and sp side. The tick is still there, at >2k, but...car sounds amazing. I was so surprised at how much more quiet it is. Makes it actually sound like my car just came off the lot! Very quiet. Even though my problem is still there, by changing the idler pulley the car runs much more healthy, and now because the car is quieter I can better isolate that tick. I used a long screwdriver to my ear on a few components, but can't seem to find it. Intake sounds good, no strange noises so I think I'm safe for now from loose PV screws. It's coming from the bottom, like...around the alternator. Maybe the pulley on the alt is shot? Maybe my other idler pulley, on the A/C side? Might just swap the a/c side idler pulley anyway- solely based on the positive effects from changing the one I did tonight.

Thanks for the suggestions and check points guys. I really don't think it's the a/c compressor and/or belt/pulley though. The A/C is completely off and it still makes that noise. It's coming from the otherside, the Alt/PS pump side. Pulley should be arriving soon.

Nah, not the A/C Clutch. I just ordered a Dayco pulley- I'll install it and let you guys know.

+1 for me too. My rear sags whenever I truck things around or if I have 4 people in the car. It's very annoying, and looks/feels awful. The car has 140K with the original shocks and springs, so that's probably got a lot to do with it too. I want a nice lift, and a nice comfy ride. Even though I don't whip the Pathy around like it's a lambo, I'd still like to keep drivability in mind. Turning, cornering, accelerating, and stopping are all things that I don't want to sacrafice too much. I was thinking about an Old Man EMU kit. Those guys seem to be well aware of drivability. I don't need a HUGE lift- I go camping, and lug heavy things/people, I don't go off-roading or rock climbing (I'd like to someday!!)

yea. I kind of think it's the idler pulley (on the alt & PS pump side). I took it off and spun it, and it does make a very light clicking noise. Under tension, I suppose this "light click" could magnify? Is it normal for the idler pulley to have a little click (under normal circumstances you wouldnt think anything of it), or is it suppose to be super smooth- without a single noise? Thanks

Hey All, Great site, I'm new here. Found out about this site from Nicoclub.com, another great site! Anyway, you'll have to excuse me if this topic/issue has already been address in another thread- I can't seem to locate it anywhere. The R50 just hit 139k miles. About a month ago I replaced both belts, plugs, fuel and air filter. Just a few days ago I noticed that when I start up the car (it's now an average of 10 degrees outside at 6am EST) there is a clicking noise. It's not the drive belts. At first I thought it might be the "power valve screws" coming loose, but I think my engine would have blown up by now if it was that. I'm currently looking at the power steering pump pulley. It sounds like it's coming from that, or maybe an idler pulley. At a cold start, the clicking is really frequent- corresponding to the engines rpms. Once the engine warms up, the clicking becomes less frequent. As I rev up the engine though, the clicking follows. Sometimes, the clicking is non-existent- sometimes I don' even hear it in the morning. I've attached a video link as a resource, hopefully you guys have successfully dealt with issue before. Let me know if there is anything else you guys need for me to do to better assist. Here is the link to the video: Engine ticking - Flickr.com
