Black2003SE Posted January 16, 2011 Share Posted January 16, 2011 (edited) rusted exhaust I've got a rear exhaust that has become detatched from the muffler assembly. Worse, it looks like the muffler assembly might have a couple holes in it. The resonators have a patch on them already. I taken pictures of the whole system. They are available on the link above. Does anyone have experience with replacing this system? Does anyone make parts that don't rust for these?

pathfounder Posted January 16, 2011 Share Posted January 16, 2011 Those components are completely shot. I have THIS and am happy with it, though I had to modify the flange that goes to the rear muffler. 1 Link to comment Share on other sites More sharing options...
tekazgtr1984 Posted January 16, 2011 Share Posted January 16, 2011 If you go OEM, this rust problem with keep coming back. Your best bet would be to go with something aftermarket (i.e., stainless steel) which is resistant to corrosion. Salt really does a number on these trucks. Living in the salt belt sucks...

adamzan Posted January 16, 2011 Share Posted January 16, 2011 Walker makes lifetime warranty mufflers. I have one and it is the stainless steel version. Link to comment Share on other sites More sharing options...
Northernpathy Posted January 16, 2011 Share Posted January 16, 2011 I replaced mine. Bought it through NAPA which was a easy bolt on with no welding needed. Was pretty easy and straight forward: http://www.nissanpathfinders.net/forum/index.php?showtopic=25920&view=findpost&p=528542 Go under there with a reciprocating saw and cut it apart to make things easier to remove. Worst part is removing the studs from the cat's. Mine were rusted solid and I needed to heat them up until they melted off. Looks like you will have to do the same. I didn't replace the cat's as mine were in good shape. Link to comment Share on other sites More sharing options...
Black2003SE Posted January 19, 2011 Author Share Posted January 19, 2011 Thanks everyone. I ended up getting the bosal aluminized steel center and rear exhaust for about $350. 1 Link to comment Share on other sites More sharing options...
kidscollegefund Posted May 3, 2011 Share Posted May 3, 2011 Thinking of doing this as my next project, current equipment is rusting pretty good. Did you notice any performance gains? Any difference in sound over original system? Link to comment Share on other sites More sharing options...
devonianwalk Posted May 4, 2011 Share Posted May 4, 2011 I'd love to replace mine as they are long over due. However, I want to eliminate the resonator. Link to comment Share on other sites More sharing options...

Roxanne97 Posted May 13, 2011 Share Posted May 13, 2011 mine has some leakage, once i get my next check its going towards a custom stainless steel dual exhaust with quad tips tucked behind my rear wheels. Link to comment Share on other sites More sharing options...
NextToAlaska Posted May 21, 2011 Share Posted May 21, 2011 Sheet metal tape is your friend if you dont want to do a full redo. Spraying your new stuff with rust check spraypaint helps alot to if its not stainless steal. Especially on the bolts and seams as those are were most leaks start.

MrT Posted May 21, 2011 Share Posted May 21, 2011 (edited) Well, I guess I'm a little late on this one but I would have kept it. That is a very common spot for it to rust through since the water collects in that flange. I can't really tell from the pictures but these mufflers come with a heat shield that rusts apart but usually leaves the muffler in tact. Either way if anyone ends up here with the same problem all you need to do is cut the flange off and use a section of new exhaust pipe (~$5) cut it to size and slip it over the two ends. Then you just put a clamp on either end and call it a day. I fixed mine for $10 and it's never given me a problem since.
