The Nameless Performance 4-2-1 Stepped Long-Tube Header improves exhaust dynamics allowing for massive gains in top end power and midrange torque for your BRZ / FR-S or GT-86. The system is 100% bolt-up to the factory exhaust or any upgraded exhaust system that is compatible with the factory header.

Development of a proper exhaust manifold for a naturally aspirated vehicle is not only about developing something that flows well. If that were the case, all headers would have primary tubing diameters far larger than the size of the exhaust port. The purpose of a performance exhaust manifold is to lay the system out in a manner that has the appropriate lengths and diameters to allow the system to build velocity and optimize sound resonance to assist in the evacuation of the exhaust gasses from the engine as well as allow additional tuning that will achieve gains otherwise unavailable with the alternatives on the market.

The biggest variation between Nameless Performance's 4-2-1 header and the competition is the use of as much of the space in the engine bay possible in order to achieve the proper primary and secondary tube lengths. Additionally, Nameless Performance is the only company who has publicly iterated through the development process over the course of a year including 7 different designs, tuning for each and sharing the results. This gives you the peace of mind that the design you have chosen has gone through a full quality review and full gamut of research and development. This R&D has resulted in fine tuning of both the appropriate diameters for the primary and secondary tubing, as well as the appropriate choke diameter for the tertiary collector and its optimal internal profile.

In addition to the unique design features noted above, the header is entirely mandrel bent (initial photos show fabricated version rather than the unique mandrel bent final version which has far less weld count) out of T304 Stainless Steel. The merge collectors are batch sorted, matched and hand fitted/welded for optimal gas merge and anti-reversion dynamics. The entire system is hand tig welded by expert craftsmen and is accomplished on a proprietary fixture which features a plumbed water jacket and argon pass-through for full gas shielding inside the entirety of the manifold. The water jacket system bolts to the flanges and rapidly dissipates heat during the welding process, ensuring a perfectly flat surface upon completion, while the gas shielding produces a perfect full-color weld inside and outside the tubing. Flanges are 1/2" Billet T304 Stainless, CNC Machined for flatness and counter-bored for perfect transition from the exhaust port to the primary tubing.

  • Q: How Much Exhaust wrap do I need?  murcielago12 2 years ago


    Hi, I am planning on getting this header soon and would like to know what the lengths of the header piping is like as I need to get the exhaust wrap for it. Thanks!

    • A: 2 Rolls of 2in x 50ft would do the trick. You can find this by searching Part # DEI 010127

  • Q: 2.5or3  Josefus0270 3 years ago


    Is this a 2.5 or 3 diameter?Is it available ceramic coating. Iam looking for 2.5 coated.

    • A: This header has a 3 inch outlet and is currently not available with ceramic coating.

  • Q: KW C38  guest55c7adeecaae52f46094c5b1 3 years ago


    Will this header work with the KraftWerks C38 supercharger kit?

    • A: This header will work with any supercharger kit that is compatible with the stock header.

  • Q: Deq  Vladboyko 3 years ago


    Will this cause a check engine light or fail the deq?

    • A: Because this header increases exhaust flow, it is possible for a check engine light to appear.
