This stainless steel performance exhaust header is engineered specifically for the BMW E30 series, including the 320I, 323I, 325I, and 325IX models. Designed to enhance exhaust flow and improve engine responsiveness, it replaces the stock cast iron manifold in tuned or restored vehicles.
The E30 exhaust manifold is constructed using durable stainless steel to resist corrosion and thermal fatigue. Its mandrel-bent tubes allow smooth internal exhaust gas movement, which contributes to reduced backpressure and optimized engine breathing. The TIG-welded flanges ensure a tight and reliable seal.
