Any good suggestions on how to fabricate the exhaust system?
I figure I can take the various bent pieces of pipe and cut and tack weld as I go.
Also thought about bending a rod in what would be the center of the pipe and have a muffler shop bend me up the pipe.
My engine is a V8 in transversly so going to have one bank a bit longer than the other so any help there would be good too.

I just thought about the angles I needed. Then I made a cardboard cutout and went to a local muffler shop and had them cut me random bent pipes. Then just started cutting and tack welding.
I did buy my headers from NAERC.

Later

I purchased a few 2 1/2/" (J) bends from summit along with 2 flex joints, then just start cutting and fitting. I just finished my exhaust last month. Take a look at my build diary if you need some ideas.

My V8 is transverse as well

jcw whitney has some mandrel bent tubing with a small radius
it will save you space if you need it. normal muffler shops are
not equipped for mandrel bent tubing

i used a mig welder and had difficulty controling the heat,
burn through.. had to do heavy welds to seal in some areas.

i tig unit would be nice.

in my case it does not matter since it will not be seen from above.

looks good Dale, thanks guys getting the pipes shouldnt be a problem though I used to work for an exhaust manufacturer
And still know a few guys there who said they could get me various pieces of tubing.
They have enough scrap pieces in one day to build my whole exhaust.
I was just looking for the best process to get from the manifolds to the tips.
Dale how loud is your car with just one muffler?
And what muffler are you using?
Or maybe Gregs idea of using two glass packs but I was afraid that would be too loud.

I later added these cats to calm it down a little # 54304

I used the magniflow dual inlet and outlet. I'm very pleased with the tone of the exhaust. someday I'll get some video.

HI:

I used prebent shapes from Summitt Racing and have all the steps outlined in my build diary for (2) different systems.
#1 uses no CATS and #2 uses CATS. My state requires CATS.

I cut the tubes with a chop saw and Dremel Tool.
Then I tacked welded the shapes until I was happy with it.

There is a video in there of the unit running with the CATS abd Dual IN/OUT MagnaFlow exhaust.
