Hey I just bought the nismo exhaust I have a leak at the muffler/midpipe connection. I tried using a regular gasket and some sealant, but still have the leak. what should I be using? seems to be a 3 inch diameter pipe??

Thanks,
Bob

 

if its a stock exhaust its 2.5" piping

 

Its not stock..its nismo exhaust. Wht kind of gasket do I need?

 

I found a 2-Bolt Exhaust Flange Gasket for a 3” application that might work for you. You might need to modify it to make it fit.

The link is below for 3" SCE:

This link is for a 2.5" from Walker:

This one is from SCE on a 2.5":

The OEM 2.5" rear muffler gasket is below:

See if these work. The Walker gasket seems more promising. It has a collapsing ring and the micro fibers to help seal the exhaust leak. Besides its a direct OEM replacement.

 

Do i need an o ring gasket?

 

Had the same issue when I purchased my exhaust...just take it to a reputable muffler shop and they'll be able to get you exactly what u need.

 

so it's not something i can buy at the auto parts store right? I've been looking at autozone,etc...I tried using exhaust gasket sealant...didnt work.

 

Gasket sealant will not work.


You must use a gasket that fits without needing to modify it.

If you have an aftermarket Y-Pipe to Mid-Pipe you will need a 3 inch 2 bolt gasket.

The problem with the 2 bolt gasket is sealing.

Since it's such a big flange it tends to not seal properly (it really needs to be torqued down)

If you get crush time gasket you need to apply enough pressure to crush the gasket shut in order to make it seal.

 

Just for future reference, the correct OEM Part Number for the "Ring Gasket" is 20691-0P600. I believe it's $12.75 and should be readily available at any Inifiniti dealership. Just a metal ring crush gasket in between the midpipe and the muffler.
