Got all my ####e together and ready to fabricate my extractors for my A15......
They will be a 4-2-1
Primary size 33mm inner diamter (1.4 wall)
Secondary size 39mm inner diameter (1.6 wall)
And into a 2" collector (will make out of sheet metal)
And into my 1 3/4" system...

This is the best example i have, courtesy of DatRats.com.au, thanks for the use Errol!!




All i have to do now is work out my radius sizes and knock up my jig on a piece of wood and rubber tube
As i'll be doing the bending ill have to make a kinda stand to do the bending in, bugger.

But what i neeed to ask is would it be ok to run my fresh 'mild' A15 with a new carby, 32/36, on the standard exhaust manifold? it hasnt been fired up yet and im just worrying im going to suffocate the ol girl to death!!
Waddya reckon?
