Subaru Exhaust Header
DynoVox Subaru Headers: Stop Choking Your Boxer
Ditch the factory boat anchors. Our T409 stainless headers slash backpressure with mandrel-bent primaries and CNC-flanged collectors - proven 11-14whp gains on EJ/FA blocks. Hear your turbo spool faster as exhaust gases rip through optimized 1-5/8" tubing.
Built For Your WRX/STI:
● Laser-cut mounting plates bolt directly to EJ257/EJ207 heads
● Clears factory crossmembers & steering u-joints
● Jet-Hot 2500° coating included (outlasts NY winters)
Whether you're chasing stage times or sharper commutes, these headers fix the three flaws in Subaru's exhaust:
Crack-prone cast iron → Our 10-gauge stainless laughs at heat cycles
Collector turbulence → Dyno-tested merge angles scavenge cylinders evenly
Rust belt rot → 0.5mm thicker than OEM flanges
Don't upgrade around the bottleneck. Header up right. Shop DynoVox - Ships same-day
