If you’re chasing every tenth, the ETS MaxFlow LW Header delivers. This lightweight version of our proven MaxFlow design uses .083" wall USA-made tubing (vs. .120") to shed weight, increase internal diameter, and unlock even greater exhaust flow—all without sacrificing strength or reliability. It’s engineered for racers who demand maximum performance from their Subaru.
