JDL 4-2-1 Equal Length Header

JDL Auto Design FT86 4-2-1 Equal Length Header

Our headers feature some of the best attributes JDL Auto Design offers through the experience of building performance products across many platforms. From the smooth CNC Mandrel bent 1.75" 16 gauge U.S. 304 Stainless steel to our signature razor's edge merge collectors. Everything is built right here in our facility by hand by master fabricators. The attention to detail that goes into every piece speaks to our passion and belief that performance is also an art. TIG-welded and back purging processes ensure the strongest of welds and provide that clean look that is admired by all. The head flanges and outlet flanges are all decked to provide superior gasket sealing and proper alignment.

***Lifetime Warranty to Original Owner***

The CEL eliminator stands for "check engine light". With the catless header, the engine light will sometimes come on with an O2 sensor code due to the increased exhaust temp caused by the lack of a catalytic converter. The CEL Eliminator simply spaces the O2 sensor up and out of the mainstream of the exhaust flow, eliminating excessive heating, while still allowing the O2 sensor to read the exhaust flow content.
