Stainless Performance Equal-Length Header Manifold - BMW E36 & Z3 Inline-6

The E36 generation wasn't just another BMW—it was the car that proved the Ultimate Driving Machine could be accessible without compromising the driving dynamics that made the marque legendary. From the balanced chassis to the silky-smooth inline-6 that loves to rev, your E36 or Z3 was engineered for driver engagement. But those factory cast-iron exhaust manifolds? They're strangling the performance your BMW was born to deliver. Our equal-length stainless steel headers unleash that potential.

Engineered for the Inline-Six You Love

Your M50, M52, or S52 engine deserves to breathe freely. Our equal-length 3-to-1 header design replaces restrictive factory manifolds with precision-engineered stainless steel runners that balance exhaust pulses and dramatically improve scavenging efficiency. The result? Approximately 5-10 horsepower and torque gains, sharper throttle response, and improved high-RPM performance that reminds you why BMW's inline-six is considered one of the finest engines ever built. Plus, you'll enjoy a deeper, more aggressive exhaust note that perfectly matches your BMW's sporting character.

Built to BMW Standards

Constructed from high-quality stainless steel with CNC-machined flanges for precise fitment and leak-free sealing, these headers feature TIG and MIG welded joints for strength and long-term reliability. Dual O₂ sensor bungs come pre-installed, and the polished finish adds a professional touch to your engine bay and undercarriage. This is performance hardware that matches the quality you expect from your BMW.
