    When you say rasp coming from the front of the motor I can't help but think you are talking about the tingy sound that comes through the header pipes themselves and has nothing to do with what exhaust system you are running.

    If I am on the right track here,,,,then the tingy pipe sound you are hearing through the headers is normal,,,,the steel tubes are thin and transmit the noise from the combustion chamber,,,,nothing you can really do about that.

    This is why GM has been making exhaust manifolds out of thick heavy cast iron for years,,,,it runs quieter and helps to supress the noise made from the combustion process,,,it's a rather large explosion going on in there,,,and this keeps the customers happy.

    With that said,,,you will get some extra noise in the engine compartment from steel tube headers.
