I have a stainless extractor manifold on my car.  It\'s a bit of a bitch to get on cos it\'s near impossible to get to some of the nuts attaching it to the head.  A manifold for an et would look similar i imagine.  Will a DET one fit?  You can buy them relatively cheaply (my SR one cost me only $120au which is next to nothing and it\'s only 6 months old)

Anyways here is a pic i have some pics of it off the car at home.  It looks crappy and brown there but now it\'s been used it\'s silver again.

You will be making it from steam bends i presume?  I dunno if you have made one before but you have to be very carefull with the alignment as you weld, my mate made one for his 3TGTE powered celica and the collector ended up horribly out of alignment.  It was his first go though, he\'s much better now, he\'d prolly make it out of stainless next time though since that\'s what his job is mostly now.
Making a steam bend manifold you might start running out of room next to the motor, my stainless mani is quite cramped as it is and it\'s walls are only about 2mm thick not 5mm.  Another way might be to do as this manifold has been done and merge the primarys early.  They shouldn\'t interfere with each other to much cos 1 and 2 don\'t exhaust pulse at the same time anways but i havn\'t seen that manifold on the dyno.  One\'s with separate primarys like mine up there are good for between 7-12kw@rw from what i\'ve seen on dynos down here.

It is probably the same brand of manifold, i believe SSAutochrome is american.  I\'m not aware of that brand but i do sometimes cut up and weld cheap spanners to get around things etc.  I DID actually manage to get the manifold on using normal tools but it just took so damn long to do up the second-from-rear nut...

yeah that is why i use the gearwrench   it is a ratcheting box wrench    takes about 5 minutes for that nut you speak of


also did you have to notch your transmission so the elbow would clear?
