Buzzing noise ???

[HTN]

Hey guys. I did a search but nothing seems to fall into this category.

Buzzing noise every 10 minutes coming from exhaust area. This usually happens when the car is completely cooled and parked.

05 lowered on H&R springs
Taitec Exhaust.

TIA

check exhaust hanger brackets and any welds esp on aftermarket exhausts.If that all checks out the sound could be coming from inside the exhaust due to a loose baffle what some would call a "blown" exhaust.

Other owners of late model NSX's have reported these strange noises. I believe they are related to the vapor recovery system for the fuel tank. It is venting or equalizing the pressure in the fuel tank. Nothing to be concerned about.

Is there any other signs that I should look out for if the exhaust is blown?

BrianK... I read that too. Hopefully it's just a noramal thing.

Thanks

Put some Bean-O in the tank. :biggrin:

My girl is a beaut, but if BEAN O is what she needs... BEAN O it is.
No smell though Doc. Is that normal? Just noise.:biggrin:

Yep, Mine does it and that's where the sound is coming from.

Thanks for the confirmation. I feel better now.

Try opening the fuel cap just after you stop and see if it still does it.

I will give that a try. As long as this noise is not harmful to the car, I'm okay with it.
Nice avatar btw.

I have a car (different brand) that tends to do this during low fuel conditions (less than 1/8 of a tank).
