Re: Performance Headers for Excel
Hi Jerkitt,
They are two different extractors, both the for X3 Excel.
The first one is for a SOHC, and the second listed is for the DOHC Excel.
The SOHC extractor has a round pipe where it meets up with the header, as it only has a single exhaust valve per cylidner.
The DOHC extractor's pipe is elongated as DOHC has two exhaust valves per cylinder, and therefore has a different shape opening in the head where it meets up with the extractors.
When you order, you must specify if yoru car is a SOHC or DOHC model, as the extractors are not interchangable.
