V3 S85 Headers
Swipe right for more info.
Long tube & equal length design
The equal length design retained the signature S85 exhaust note, while being the best performing header solution on the market.
F1 style collectors
The collectors were updated with inserts for bolts for a reliable seal.
Fits with OE sensors
Bungs for pre-cat, post-cat and temperature sensors were cut, fitted and welded to the headers.
TIG welded 304 stainless steel
They are TIG welded and made from 304 Stainless Steel. Each runner is individually tagged and aligned to slip into the merge collector.
Mandatory Tuning
Sal's own Stage 3 tuning specifically developed for the V3 headers uncork massive top end power: expect gains of up to +/- 70whp over stock with tuning.
I've bundled unique packages including the AlphaN variant of Stage 3. It's what I run.
Installation Notes
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.
Build Journal: Special Series
The zenith of BMW M NA engines was still restricted.
In this Special Series, I review the OEM restrictive design along with the evolution of Sal's catless long tube and equal length design along with my unboxing impressions.
I share installation notes in collaboration with InnovAuto, take a dive into the specific tuning maps developed by Sal for the headers and share my driving impressions.
TL;DR: It got even madder.
Enjoy,
