LS2 Exhaust Headers
Discussion
Num 3 should just be reaward of engine mount, near side no a problem as head offset gives an extra 25mm. Have also moved 1 + 2 out a bit to balance the lengths not sure how important it is. Not much room between collector and engine / chasis so hope engine does not move too much on mounts.
Simon,
Good stuff! Who's gonna weld em up for you, or are you gonna do it yourself?
I picked up my exhaust last night, stock cast iron manifolds with 2.5" system running cats only... this is to get through emissions... headers and hiflow cats and 3" is phase 2.
I worked with my fabricator on the weekend to mock up the exhaust and tack together on the car, he took it back to his shop to fully weld. I bought mandrel bends from an Ebay shop in OZ and had em sent up here, those mandrel bent pipes are great...

Here's an update on the headers.
the parts came at lunch time
dry built one side up ready for tack welding
fitted to car
NS was easy no mods required, OS was a bitch had to mod some tube to miss engine mount but got there in the end. Now waiting for the Exaust boxes and cats to come expecting them thursday so when system fully tacked up will take it to someone who can weld!!

Will these fit LS1, LS2 and AFR heads ??? if so any Idea how much for just the headers ??
As far as I am aware all of the LSx engines have the same mounting pattern/flange design. The different heads may have different size/shape openings though so you may want to check that to optimize airflow out.
