So I have had the true dual SES Exhaust on my car since early 2005. Over the past year, it has been rattling like crazy. The worst appears to be below 2k RPM, but sometimes it is just rattling whenever I am giving it gas. I have been over and over it and I cannot seem to figure out what the problem is. The pipes don't appear to be rattling against the car or each other, but I can't come up with the issue. It almost sounds like the rattle is from INSIDE the pipes, like maybe they are dual walls and one has come loose.

Any suggestions? I've adjusted the pipes half dozen times, re-supported the hangers, and still can't figure it out. It is ruining the car for me. PLEASE HELP.

 

Try the Injen rattle fix here:

im having the same problem but with the 1986c version. but i still love this exhaust!!

 

I am going to try this fix this weekend...I'll let everyone know what I find out.

 

I have not been able to find these parts anywhere (the parts in the link)...can anyone help me with this?

 

I got these from Performance Nissan in Duarte, CA http://www.perfnissan.com/

Had rattles too, but thanks to Jason at Performance it's GONE!!! I got from him the ff:
1.) DAT20722AF400 Black L Bracket - same exact one located on the left side, but I did not have one on the right. It pulls up the right pipe & holds it secure.
2.) DAT089111082G Nut hex
3.) DAT20651AA000 Mounting rubber bushing
4.) Flat alum spacers (6) for the black cross member located at the middle of the car underneath the 2 pipes (it needs a 1" clearance) & the spacers prevents it from hitting the pipes.

 

Hmm... I've got the 1985c on my Z, but no rattle issues...

 

awesome...thanks dude
