    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.

    • New Design for 2019
    • Increase in mid-range hp and tq compared to 4-1 design while maintaining strong top-end power
    • Modular design works with OEM and Aftermarket over pipes
    • 1.75″ Primaries / 2.00″ Secondaries / 2.50″ outlet
    • 15″ Convergent merge collectors for high velocity
    • 304 Stainless Steel tubing
    • Precision Tig Welded and back purged for maximum strength
    • Available with Cerakote thermal coating options

    ***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.

    **Special Order Notes**

    All manifolds, hot part kits, custom intercooler kits, and full turbo kits are built upon order unless otherwise stated items are in stock. Please allow 4-6 weeks for completion of said parts. Build times are also subject to change without notice depending on current workload.  If you have any questions please don’t hesitate to contact us

    Worth the wait
    It took about 7 weeks to get my header but it was well worth the wait!

    This header looks beautiful and performs amazingly especially with a tune custom made for this header! Almost completely removes the torque dip and adds a great sound note to an otherwise stock car.
