Header and Exhaust – 3 Hours

Installed driver’s side header and exhaust, the passenger side header requires a CO2 bund to be welded in place before this is installed. After checking the EFI wiring harness and the fact that the passenger foot box is smaller the decision became easy to select the passenger side header as the location of the CO2 sensor. The headers are manufactured by BBK.


Many Cobra owners complain that header bolts come loose and even fall out, determined that this would not happen this installation is using Stage 8 locking fasteners, basically a grade 8 bolt uses a retainer which slips over the head and is held in place with a snap ring.

With the header installed the exhaust pipe was bolted in place, although the exhaust pipe is self supporting the vibration hanger still requires installation.

Again many Factory Five owners have complained that the exhaust pipes don’t mount parallel to the ground or run parallel to the chassis, after installation simple checks found this not to be the case with the driver’s side exhaust pipe, being zero degrees to the ground and parallel with the 4” main chassis tube.

Here’s hoping the same can be said when the passenger exhaust pipe is installed.

The first of 2 grounding straps was also installed prior to installing the passenger side header, the engine mount has a pre drilled hold to mount the strap to the frame, prior to installation the powder coating and engine block paint was removed with a Dremel to provide good continuity, once attached the area was then coated with dielectric grease to stop corrosion.
