New Exhaust "DING"

Shwimpy

Sorry for drudging up a year old thread, but did you just get the one faulty resonator replaced or both for even flow? I'm experiencing the exact same issues with a newly installed r-tune cbe.

I just installed the R Tune as well over the weekend. I noticed a sort of "ding" noise a couple times on the first drive on the highway, I assume the exhaust wasn't fully heated up yet. Since that first time I don't recall noticing the noise while driving. Do we think this could possibly be part of break-in?

I will hear creak or ding noises after I've turned the car off and it's cooling down, but as we know metal contracts and expands with heat, it being a multi-piece system it's bound to make noise.

Where did you guys buy your R Tunes from? I got mine from CZP and they said they hadn't heard of this issue happening, but I did forward them this thread to look into it just in case. I am certainly keeping my ear out in case the noise starts to happen more frequently on the road.

Mine was purchased from Dynosty. After a few weeks I'm use to the noise but it'll still get pretty damn annoying near a wall. I'll post an update if it ever goes away (hoping a few WOT runs might blow something out).

Just to follow up, the noise on mine has actually gotten more persistent. I've contacted CZP about it and sent them a video. They agree it isn't normal and have sent a report to Nismo. I'm going to try to return mine, I've already placed an order for a Fast Intentions CBE with 18" resonators.

I thought it was from the expanding/contracting of the heated exhaust as well, but it wasn't (well, not in the sense of normal operation--obviously it was expanding/contracting within a faulty resonator). It was a very loud and noticeable "DING" that happened about every 45 seconds and lasted for several minutes after I shut the car off. It was definitely coming from one of the resonators. We spent a long time listening and isolating. After the resonator change, I've not had any more issues and I LOVE this exhaust.

I bought my exhaust from Z1.

Following up for anyone else experiencing this issue. After a year with them installed and over 15k miles the noise isn't so bad. Only ever hear it when it's hot out, and the Z is ran for a while. It definitely calmed down and 90% of the time my windows are down and I'm in a lane next to a wall so I would hear the echo pretty well. So there is hope without replacing the resonators.

It was just one resonator as far as we could isolate; however, I had them both cut out and just replaced with the stock ones. I'm sorry that you're experiencing this, as it's very frustrating. It seems to be a QC issue on the manufacturing end.
