Developed with CAD software and simulations to maximize power across the rev range. Short primaries and a single secondary reduce header volume so exhaust pressure builds quickly. A symmetrical 4-1 design keeps exhaust velocity high and consistent as RPMs rise. Compared with long-primary, double-secondary designs, it spools faster, improving throttle and boost response and holding power higher in the rev range. Special order; contact for lead time.

Fitment: Subaru WRX STI GD (2004-2007); Subaru WRX STI GR/GV (2008-2014); Subaru WRX STI VA (2015-2021)
