BBK's tuned mid length headers for the 2011 Mustang feature all the great features you've come to expect from BBK headers over their many years manufacturing quality made in the USA exhaust components.
Starting with their 1 piece laser cut 3/8" flanges for a perfect leak free seal. BBK used large 1 3/4" mandrel bent tubes for maximum flow.
When combined with their after cat X-pipe gains of up to 14 horsepower have been achieved on an otherwise bone stock 5.0L Coyote engine. You can expect even more gains on highly modified vehicles. Gains start early in the power band for an increase in power over the entire RPM range.
BBK's after cat X-pipe bolts directly after the factory catalytic converters for an easy bolt on installation.
