The S85 and the S65 were the pinnacles of naturally aspirated engine development by BMW M.
Their engineers managed to create equal length headers for the S85 and S65 giving them their signature sound.
However, the older V10 design had its primary cats are built into the headers, right after the merge collectors.
The design immediately impacts exhaust flow - inhibiting potential performance from our V10s.

Salman developed a Stage tuning map to tap into the optimal performance potential of the V10 M5 fitted with V3 headers. He also eliminates the Check Engine Light (CEL) from your dashboard.
Red is stock.
Green is headers without tune.
Blue is headers with stage 3 tuning.
This journal entry was done in collaboration with the guys at InnovAuto who did the installation.
You'll find tips, tricks, notes and the required hardware.
InfinityDesign's unique product design and engineering is crafted by the grand-daddy of the most popular S85 products and tuners to hundreds of S85s.
As a former Evolve co-owner, he took part in engineering the headers & e-tronic exhaust system, cat deletes, carbon intakes, v8 supercharger kits and tuning maps during the 2000s and early 2010s.
