1997–2005 Audi 2.7L B5 C5 Bi-Turbo Stainless Steel Header
Mandrel-bent stainless steel header designed for the 2.7L twin-turbo engine with equal-length runners for optimal scavenging. Built from 304 stainless to resist corrosion and thermal cycling. Direct bolt-on design minimizes custom fitment work.
✓ Stainless Steel Construction✓ Equal-Length Runners✓ Direct Bolt-On Fit
Key Features
Equal-length primary tubes — Keeps exhaust pulse timing consistent across cylinders, reducing back-pressure and supporting power delivery.
Mandrel-bent design — Smooth bends eliminate turbulence and flow restrictions that stock restrictive bends create.
304 stainless material — Resists thermal stress and corrosion from repeated heating cycles and condensation.
Does this require any welding or modification to install?
No welding needed — this is a bolt-on header. You'll connect it to the turbo inlet and exhaust system using factory mounting points. Verify all bolt holes align before final assembly.
Will I need a new gasket and hardware to complete the install?
The header itself comes bare. Source a quality exhaust gasket rated for bi-turbo applications and stainless steel bolts appropriate for your system — these are not included and vary by your existing exhaust configuration.
Can I paint or coat this after installation?
Stainless steel doesn't require coating for durability, but if you want a finished look, heat-resistant ceramic or high-temp coating can be applied post-install. Let any finish cure fully before first heat cycle.
