After Bugpack was sold to Empi we came to the end of our economic header system from Bugpack after going through all of our stocks. Because Empi does not supply the quality we like, we teamed up with Tri-Mil for a good quality-price sports exhaust line in our economic range. Tri-Mil is a long time in existence exhaust manufacturer and is very happy they have with BBT now a very strong distributor for the European market.
