i managed to get one finished. i still have to figure out wether or not im going to build my collectors or try to buy something. most likely it will be a combination of both.

the tubes are stainless 1 7/8" to 2" step. the flanges are 3/8" mild steel. i didnt use stainless for the flanges because i started on this during my week off, thanks to the wildfire, so i used what i had on hand. the bends are not uniform so fitment was a PITA. i had to back purge. if fit is perfect, i can get away without purging (and no sugaring).

I would build you own merge collector. This video looks like it isn't too difficult.

Gee if looking at your home made front cross-member and A-arm suspension mounts didn't convince me looking at these headers definitely convinces me that you know how to weld. Great job!

Yes he does!!!!!! The headers are bitchin! Look for collectors before you make them, Way less $$$$$$.

Speedway is a start.

Dave???? Home made means nothing when you know what it takes. Laughing I don't mean disrespect either. Keith has a clue and that is all.

i usually tell people, when they ask "where did you get that ?", "its just some of my home made junk" Laughing

the video was for a 2-1 merge. however, it led me to this one.... http://youtu.be/xewA7QHWp1c. depending on what i have left in the way of bends, i might try that.

as far as buying collectors, the only ones that i could afford are the plain stamped ones. a decent merge collector is about $325 each. i did come across this place.... http://www.megsexhaust.com/exhaust_system_kits.html

Great - now I know where to go to when I need my next set of turbo headers made Laughing .......... They look great and like others mentioned I know what kind of work it took to get there. Glad you got some time to work on it although the fire is a sucky reason to have time. Clay

left side is done, except for trimming the ends. now on to building the slip-on collectors.

in case anyone is wondering, i used eleven J bends (five 1 7/8" and six 2") and a 5' piece of straight 2" tubing. what you see on the floor in the back ground of the third pic is all that is left of the 2" J bends. i have about 12" left over of the straight tubing. for the 1 7/8", i should have bought U bends instead. i have several straight pieces about 10" long left over.

DONT TRIM THE ENDS!!!! DONT TRIM THE ENDS!!!!!!! If you are planning on slip on collectors, they are WAAAAAAAYYYYYYYY easier to slip on if the lengths are slightly different, because you can slip it on one tube, and then pull it over to line up the next, and so on. I made a set and stupidly wacked them all off even, and the collector is almost impossible to slip on.
It basically turned it into a 2 man job every time.

Laughing ..... well, i did trim the longest. it was nearly an inch longer than the shortest and it annoyed me. thanks for the tip though Cool .

i finally got those damn things in the car. had to pull the motor to do it. it seems that i got one tube on the right side higher than the rest. no way im fixing that sh!t now. and, believe it or not, the starter can be removed/installed with the header in place (figured that out the hard way Embarassed ).
