Scraping/grinding/rattling noise after installation of Gemini CBE

dirtygushikid · 09-15-2012, 03:38 PM

I recently installed my Invidia Gemini CBE and after the second day of installation I started hearing a scraping/grinding/rattling noise ( I can't really pinpoint the exact sound it makes). The sound happens just before I let off the clutch at first and second gear and when I turn left or right at low speeds. Also, it makes the noise when I rev it from standstill. Once I hit 1200 RPM it makes the noise then goes away. I don't really want to take it to the dealership since I am worried that it might void the warranty but I will take it if it is my last resort. Before I take it I would like to hear from you guys and your thoughts and opinions on the subject.

Did you secure all the heat shields? Sounds like something is loose.

I saw the mechanic put everything together. it seems like he had everything tight.

<Shrug> Get the car up and start shaking parts of the exhaust, or just run it and listen. If everything is tight, there could be something loose inside the mufflers/resonators perhaps.

After I got mine installed, I had to fight a few small leaks near the X pipe (G sedan), but that didn't sound like any scraping/grinding/rattling noise.
