ACE is an exhaust specialist that specializes in high quality engineered, handcrafted, and hand welded exhaust systems. Their work is renown in the Japanese and European motorsport world.

ACE prides itself in creating limited quantities of the 4-2-1 header for the Subaru BRZ / Scion FRS / Toyota GT86 and can output two headers per month. One man cuts and hand seam welds all the tubing for this header, making it one of the most prestigious headers to obtain for the 86 platform. This attention to detail is paired with calculations, analysis, and extensive testing to produce an exhaust unit that produces power throughout the powerband. The smooth powerband can only be found in ACE's detailed calculations, routing, cutting and welding methods that can only be reproduce by ACE themselves. Each header is serialized with the official ACE logo and handcrafted by ACE's top welder.

CounterSpace Garage (CSG) has independently tested the ACE 4-2-1 Type A header with the 350 collector on a complete factory 2015 Scion FRS to verify and validate the performance of this header. The findings can be found in this FT86Club thread:

The ACE header comes with the 4-2 header section and a 2-1 overpipe section. By utilizing the 350 collector, this 2-piece header is a long tube equal length header that maximizes power throughout the rev range.
