Re: Bad News
As said previously, they've got the story wrong, or it total BS.
Apart from anything else, OEM exhausts are impossible to obtain for older vehicles, so this would essentially defect anything older than probably 10 years.
At the end of the day, if it isn't illegally loud, and is still filtering the appropriate gases, a better performing exhaust is better for the environment (more efficient=less fuel).
