Hi,
Yesterday I replaced cats with test pipes on my NSX. After I have done that, every time when I rev the engine above 3000 rpm and release the gas, some kind of the rattling noise came up.
I checked the exhaust pipes, there is no contact between piping and chasis.
Does anyone knows that is problem? Is it engine or tranny problem?
thank you
