Stainless Steel Sport Exhaust Headers for BMW 320i/325i/330i/Z3/Z4 with M54 6-cylinder engine, and manual or automatic transmissions. Models with air pumps may require modifications. These high-performance headers were developed in Germany and are manufactured out of heavy gauge T304 stainless steel for long life. They are intended for track and off-road use only unless you weld in catalytic converters. The kit comes complete with gaskets. Left-hand drive models only. Not for four-wheel drive models.

Replacing or upgrading your exhaust header is necessary for both engine performance and sound. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound. FLASHARK offers many products to help you create your own custom engine headers. It's really easy and convenient to use: direct bolt-on, no modification needed. 


Exhaust Header VS Manifold, which is the better choice?

The structural differences between exhaust headers and manifolds are the material and size. From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.

Great fit

I installed on my 2004 BMW 325i, they went on easy and they fit great, I did purchase the steel E36 gaskets with grey Permatex, it was recommended by someone on YouTube. I also doubled the gasket that goes from the header to the exhaust pipe, but I didn’t use the paper gasket, I purchased the steel gaskets, also recommended by someone on YouTube. Works great, very happy with my purchase.
