"Thank you for the inquiry. We have no plans at this time to offer a GB on the '88 - 07 models. If and/or when we do, it would require a minimum of 10 systems. The previous and last GB offered for the '88 - 07 models was for an extrodinary price and very special tuneable muffler. If we were to offer that particular design again, it would be in excess of $500.00.
Sincerely,
Area P "
