I have the Pantera Performance mufflers on my car. They are well made. I agree with Chuck and Larry, these are not quiet mufflers, or it least they are not on my car. I am not sure how much the motor size, headers or exhaust pipe size can affect the volume so that could be a factor. When I got these mufflers, I looked through the inlet and you can see right through them, so they aren’t restrictive.
