Z1 test pipes, I broke the first one in a speed bump. The second lasted a few weeks. Number just ripped itself apart no idea. The stock one has been on for two years now an no issues. I'm just waiting to get an xyz pipe.

 

You're not looking hard enough OP

Plenty of them to be found if you make a WTB in the marketplace or just be patient as others have suggested

I am sure (like most NISMO parts for our car) the exhaust has been long since discontinued

 

I have a S-Tune exhaust on my 03 that I am looking to trade for a single exhaust or possibly sell for the right price. PM me if anyone is seriously interested and I can send pics and more info

 

My nismo exhaust rattles so much, that you cant even hear it --with test pipes. I could probably hear the muffler rattling from 1/2 mile away. I can't even start my car late at night. Must be the internal baffling, but my god it's bad. Not sure I'm the first one to have this issue.

Striking the muffler tips softly with a rubber mallet is unusually loud. Since it's so expensive, any good options on repair? I think both muffler tips/pipes have broken off inside the actual muffler. Outside welds look good still.

 

Does the s tune use just the o ring for the mid pipe to muffler or is it o ring and gasket?

 

Just an o ring. When I took mine off to swap my diff I was able to reuse it.

 

How long have you had it for? What is causing the rattle? Something internally or it is hitting the heatshield? Maybe your exhaust hangers are shot and it's bouncing around underneath your car.

4 years here with no issues on mine.

 

Thanks man. Do you know the length of the pipes that go from the muffler to the tips? I got a used s tune and the tips are extended but the original bent part was cut off and replaced with a longer pipe.

 

Probably 1 year. It's internal. The muffler tips end up breaking off from the internal baffling it seems like. I've went through that exhaust hundreds of times trying to isolate every possible point of contact, tried poly hangers, new rubber ones. The exhaust shakes so much that at 2k rpms the test pipes contact the chassis. When the exhaust doesn't contact the chassis, the muffler tips just buzz violently. It's embarrassing. It's still my favorite exhaust.

Is the piping Titanium? It's non-magnetic, which seems like titanium.

 

Well if you bought it from Nissan it comes with a 1 year warranty.

Judging from what you just said, the test pipes could be the culprit. It is known that pairing the S-Tune with test pipes can cause cracking in the pipe, so if you have not figured out where the issue is I would look directly at the test pipes and y-pipe.

The piping is stainless steel. It is non-magnetic. I believe that is a way to see the quality of an exhaust, if it is magnetic, then it is garbage. Don't quote me on that, but I believe I remember reading that somewhere.

 

I second this. My S-tune Y-pipe cracked with the Kinetix HFC installed on oem exhaust manifolds. Kinetix HFC-->Tanabe Y-pipe-->S-tune back exhaust. Best sounding car I've ever owned.

EDIT: Oem manifold outlet (2"), Kinetix HFC inlet/outlet (2.25"), Tanabe Y-pipe inlet (2.36") outlet (2.78"), S-tune exhaust (3"). Perfect stepped configuration.

 

But if you are keeping the stock cats no need to change the Y-pipe.

I would only change my Y-Pipe if I was planning on getting HFCs or TPs.

 

Pairing the S-Tune with the Motordyne XYZ gives it a really deep, clean sound that is too good to not step on it every time.

SQualZ, I can't tell you how many times I listened to your youtube clip because you captured the sound so well. It definitely made me was the S-Tune more and more. I even created my ringtone out of it lol.

 

Haha thanks!

 

OP one just popped up in the classifieds in great condition.
