Created With Performance In Mind

As is the goal with building any header, the purpose of designing the N52 Performance Header was increase horsepower and improve overall performance. Our header does a tremendous job of freeing up untapped horsepower that the BMW N52 is capable of producing. After many dyno runs and recorded results, the data validates the Active Autowerke N52 Performance Header as must-have BMW performance part for a noticeable and powerful upgrade.

Material & Durability

Suitable for either naturally aspirated or supercharged applications, the N52 Header by Active Autowerke is made entirely of 100% 304 stainless steel. With this header, worrying about durability is a thing of the past.

Installation

Is installing the header difficult to do? Not at all! Robust exhaust flanges with recessed mounting holes make the installation of your N52 Performance Header a breeze. With a few quick turns of a ratchet, you will be well on your way to feeling the additional horsepower.

NOTE:u00a0Active Autowerke GUARANTEES that each and every N52 Performance Header will be a precise fit. Every Active Autowerke N52 Header is test-fitted on our N52 motor jig as part of our quality control.

Hardware:

As far as mounting hardware is concerned, this system is absolutely complete. The BMW N52 engine uses a single-use oval shape gasket to help seal the exhaust manifold against the exhaust port u2013 a floating design that also self-centers the exhaust flange as it is being torqued. Reuse of this gasket is NOT SUGGESTED which is why we provide you with SIX new gaskets as part of the installation hardware.

Also included are two fiber gaskets for where the header meets the remaining sections of the exhaust system. Copper locking nuts for the header to mount against the cylinder head and mounting bolts w/nuts to secure the header to the exhaust system are included as well.u00a0

NOTE:u00a0The factory exhaust catalysts MUST be removed in the process, making this solution recommended for off-road and racing applications ONLY.There will be a CEL without Active Autowerke software upgrade

NOTE:

This exhaust may not easily fit some of the XI (4WD) and Station Wagon Models – welding may be required for proper fitment of the exhaust to stock pipe.
Exhaust system requires cutting of the factory pipe for installation. Dimensions and cutting points are highlighted in the instructions.
Some models have a round tubular pipe that makes the installation seamless. Other models have an oblong shape and will require welding instead of clamping.
