BBK's H-type mid-pipes have been helping owners get more power from Mustangs with BBK full-length headers for quite a while. Now, however, BBK has added the Extractor series high-flow mid X-pipes to the party. They're made from fully aluminized 2 1/2 in. tubing, and benefit from the improved flow characteristics of the company's die-stamped X-chamber crossover. For good fit and ease of installation, Extractor pipes are computer mandrel-bent and fitted with die-stamped flanges. Street applications have catalytic converters; off-road-only types do not.
