JDL FT86 4-2-1 Equal Length Header

Looking to maximize mid-range horsepower and torque for the track? Look no further because JDL Auto Design has you covered. Even better is this header still maintains solid top end power for those long straights. The FA20 known for its "torque dip" is virtually eliminated with any JDL header but the 4-2-1 really broadens this area of the RPM range. Don't think the FA24 is left behind because it too really elevates the power everywhere even though it suffers far less than the FA20 due to FA24s increased displacement. The JDL 4-2-1 header is a handcrafted stainless steel masterpiece that offers precision and attention to detail that only JDL can provide. Available for both generations of vehicle to maximize power potential whether naturally aspirated or supercharged.

Pro Tip: Consider replacing your OEM manifold gaskets especially if the vehicle has some years and miles on it. Make sure to add them before checking out. If the "Subie Rumble" and top end is what you are after, make sure to check out our UnEqual Length header variants.

**NOTE: Some European regions mandate an EGT sensor. Our header DOES NOT include a provision for the EGT sensor. The header will still work but it is the responsibility of the end user to have an EGT bung installed locally should our header be purchased.

The currently available design is NOT compatible with the Verus oil pan. We are working to update the design for compatibility. The current design is however, compatible with the Formula Delta oil pan. The redesign will be compatible with both oil pan options in the near future.

Lead Times: We here at JDL Auto Design strive to bring the community some of the best products on the market and we do so through craftsmenship and attention to detail. Everything we make is handcrafted on a built-to-order basis. This means raw material goes into production soon after placing an order and then brought to life with our artisan fabricators skillful effort. We are a small crew of enthusiasts that work as quickly as we can and generally lead times are 4-6 weeks. We often ship orders much sooner. There are periodic scenarios where suppliers of raw material or components may also have lead times that are outside of our control and this can affect our overall ability to meet an estimated lead time. While rare, it does happen. Regardless of lead time, you will always receive your order and it always ends up being worth the wait. Don't settle for what is in stock but rather wait for the best!
