JBA Headers and Exhaust

JBA Headers, Exhaust, Mid-pipes, Mufflers, Exhaust Tips, Ignition Wires and More

 

JBA is one of the most trusted names in the aftermarket exhaust industry because of their commitment to manufacturing excellence. The JBA product designs are original, innovative and always deliver. Power, quality, fit, durability, and emissions legality are what JBA is known for. In 1987, those qualities were not present in the header or exhaust industry, so JBA set out to build high quality products to meet the needs of the growing street performance market. Originally developed for the 5.0L Mustang, JBA's replacement Cat4Ward headers were engineered with heavy-duty features, easy installation, a durable design, and emissions legal status that made them an instant hit with automotive enthusiasts across America. As demand grew and emissions regulation increased, JBA saw the need to broaden their product line to cover most popular GM, Ford, Dodge, Jeep, Nissan and Toyota vehicles. JBA has applied their manufacturing philosophy and build qualities to offer the most complete line of quality 50-state emissions-legal exhaust products in the industry. Today, JBA offers a variety of products to meet the demands of the performance enthusiast; JBA Cat4Ward Headers, JBA Performance Exhaust Systems, JBA PowerCables ignition wires and our new line of Long Tube Race Headers, all available from Accesspeed.

Down-Pipes

 

What is a down-pipe?

A down-pipe is an exhaust tube that directs the exhaust gases from your vehicle's turbo “down” into your exhaust system. The downpipe typically bolts onto the exhaust side of your turbo housing, and connects at your mid-pipe section. Some down-pipe exhaust brands include catalytic converters and others are simply straight-though pipes that bypass and/or eliminate the catalytic converter.

 

Does a down-pipe make your exhaust louder?

Yes. Most aftermarket down pipes have a straight-through design that will reduce backpressure and increase exhaust efficient. This makes your exhaust louder with a more aggressive note.

 

Does a downpipe increase horsepower?

An aftermarket down-pipe on any turbocharged engine should increase horsepower. In most cases, the upgraded down pipe will allow the turbo to spool quicker and hold a higher boost level.

 

Does a downpipe increase fuel economy?

Like most upgrades that reduce backpressure and allow exhaust gasses to exit more efficiently, you can realize a fuel mileage gain. However, most Accesspeed customers are simply unable to keep their foot out of the throttle long enough to see the fuel economy improvement.  

 

Are down-pipes legal or illegal in my state?

If a down pipe requires modification or removal of the OEM catalytic converter, it is likely not legal. If the down-pipe you want to order is not 50-state legal (CARB-approved) with a proper EO#, it is most likely illegal in your state. We recommend checking your state laws to verify prior to purchasing.
