JBA Ford 390-428 16 Bolt FE Rectangle Port Header Gasket - Pair

JBA PERFORMANCE dates back to 1987, when they adopted as their goal the designing and manufacturing of an aftermarket performance exhaust product that was smog legal yet powerful enough for the performance driver and of high quality and durability. The result of this endeavor was the direct replacement "SHORTY” HEADERS for the 5.0L Mustang proving to be a boon to the performance driver who loved their Mustang but had to pass emissions standards in their states. This Mustang header was the solution that proved to be easy to install and of inimitable quality. Emboldened by the success of the Mustang header and with an ever-increasing need for emission legal products, JBA PERFORMANCE launched new exhaust products for other vehicles, from Mustang and Camaro headers to exhausts for GM, Dodge, Jeep, Nissan and Toyota. Today, JBA exhaust products are the most comprehensive in the 50 states for being “smog” legal, and they have never sacrificed performance or quality. In 2008, JBA PERFORMANCE became part of the well-respected PETRONIX PERFORMANCE PRODUCTS group that can trace its roots back to 1962.The resultant merging of JBA PERFORMANCE with PETRONIX afforded a more efficient production process. JBA exhausts are renowned in the aftermarket performance exhaust industry, most notably for the CAT4WARD HEADERS and JBA FIRECONE merged collectors that were a hit at the 2004 SEMA show. You can get these Mustang headers for your V-8 on the LM PERFORMANCE website with its patented FIRECONE collector that eases the transitions between the primary tube and the collector maintaining the direction and speed of the exhaust flow culminating in increased power.

When you add a JBA exhaust to your iconic Mustang, you might wonder what kind of power gain you can expect, and on a fuel injected V-8 engine, you should see 10 to 25 horsepower gains and about the same in torque. With a V-6, on the other hand, the gain will be between 10 and 15 after you take into consideration your car’s condition and other aftermarket upgrades you might already have. The famous CAT4WARD shorty header for your Mustang might be just the answer to your performance needs with its bolt-on design and 50-state smog legality. Peruse all JBA exhaust systems on our website and decide which Mustang or Camaro header is best for your driving needs, and let the team at LM PERFORMANCE get you what you want at a competitive price.
