THE 4N 6-1 F1 N52 HEADER
4N Motorsport is excited to introduce what we believe is a first for the N52 platform: a 6-1 equal-length, sequential-firing, stepped header design.
The development goal was simple: create the highest-pitched, best-sounding exhaust note possible from the N52 while maintaining excellent exhaust flow and minimizing restrictions at higher RPM.
The 6-1 collector design is engineered to take advantage of high-RPM exhaust scavenging, where this configuration really begins to shine. Incorporating a stepped primary design required extensive development and testing. The steps are designed to help maintain midrange performance while allowing the system to flow like a larger-diameter header at higher engine rpm.
DEVELOPMENT & TESTING
Development and testing are ongoing in the shop Z4 E86. As we continue refining the setup, we will be sharing:
Dyno results and horsepower data - currently 292HP 7,650rpm w/n54 intake manifold
Graph comparisons and performance analysis - videos coming soon
Technical information and development updates - fitment videos posted to social media.
Exhaust sound clips across our social media channels - posted to social media.
We’re excited to bring something completely different to the N52 platform and look forward to sharing more results.
Thank you for supporting 4N Motorsport!
