The Nismo Sounds Sick

Apollo8642 · 03-25-2014, 05:48 PM

I had a friend that's Honda made that same sound. Check the heat sheilding around the exhaust. She had a rock stuck in her's, but they do come loose from time to time. I'm also guessing that that sound is only coming from the drivers side?

Turns out the “rattle” in the Nismo (sounds like a marble going around inside of a washing machine) are parts that have broken off inside the catalytic converter. The good news here is it is covered by an 8 year 80,000 mile Federal warranty.

Talked to a friend who has a 370z and he had one replaced about 6 months ago. Not sure if this is happening to a lot of you but please do beware.

Cheers.

Interesting. I am surprised it didnt get worse as RPM's increased. Glad it is nothing serious.

Maybe it did but you just couldn't hear it. Definitely could hear it as RPM's decreased or at idle once it got a little warm. Here is a pic. If you look closely (darker area) you can see some material covering the upper left side of the opening to the cat. I figure this was my "marble" going around and around as exhaust gas was flowing though it.

I am just glad it is over and the price was right.

I was thinking something like header shield or loose bolt around there. Glad it was fixed
