Brushed stainless steel UEL headers & over pipe for your Toyota GT86 or Subaru BRZ. You will notice an increase in performance, excellent torque improvement at mid and high RPMs.
These will also change the note of the system, giving you THE crisp refined boxer rumble of the FA20 engine!
- 1″5/8 unequal length headers
- 4-1 design
- 2.5″ pipe work after collector flange
- 2.5″ over K-frame pipe
- Brushed stainless steel
- Comes with BNG-08 O2 sensor adaptor
Thanks to the O2 sensor adaptor these will not give a check engine light (CEL). For best performance gains you should get a tune after installation. Proper tune will approximately double the UEL benefit in lower RPMs, almost completely fixing the unpleasant torque dip.
We recommend to replace the rear muffer with XForce cat-back system (available here). With stock exhaust, you will get increased torque, but the boxer note will be muffled such that the car will sound like stock.
