Regarding the CL (collector box) it calculates out to 5.761", my question is what is that measuring... the length of the part, the length of the opening in which pipes are merging?

Is it worth getting stainless pipe, it really doesn't seem that much more if you look at some sort of heat resistant coating costs with steel? I really like that look of spring held joints.

Pretty rad man. I have a 72 toaster and love it. I believe Butch Walker (famous Atlanta, GA rock n roller) has a cafe'd toaster:

exhaust

Today I got a few parts of the exhaust cut and staged up... It had a 2 to 1 Luftmeister when I got it, but the headers were a banged up so I needed to figure something else out. Found a few stainless mandrel bends on the cheap.. Ended up going with stainless after calculating its cost vs. needing some sort of coating on the mild steel version.. Stainless was waaaaay cheaper.

Staged up the collector to roughly what I was thinking. It is offset to get to the oil drain plug as well as to even out the length of headers due to the left on being set forward. Cut strips of board to figure out the angles I needed.

After a few cuts this is what I've got..

Aaaand the underside. Need a couple more bends to snake out the side between the stand and frame but its a start.

I think I will install spring joints between the collector and headers

Thanks for lookin'

Damn Dude, that looks beautiful! I love spring joints as well, so much from me!

Thanks, i was getting a bit depressed with my lack of progress... but I'm pretty happy with where it's going.


Anyone.. Do I need to be concerned with making an oil collection can?

thanks.

Are you Sure you will be able to get that oil pan off with out disturbing the pipes? Oil change won't drip on hot pipe?

It does look nice. I like custom exhaust systems on Beemers.

Yea, not a problem... the collector is well to the side of the drain plug, and when the pan needs to drop it will be an extra 5 mins tops to pull the pipes back and to the side.



I sure hope I don't have to do it again as my arms are noodles from hacksawing and filing... AAAnd just realized I have to have a different gas to weld stainless



and thank you.

I have never been interested in fabbing stainless exhaust. I have always kept my stuff painted. It isn't that hard? I never had a problem with corrosion but I never packed my silencers either. Some say they run better packed. They sure are quieter!

I got ya, just wondering why different gas, but that explains it.
I just love the aesthetics of the pipe layout! gonna be one bad looking setup!

Wait, is it possible to TIG with what I have for mild steel? Is it possible to stick weld them w/o a gas?

I would not weld them with stick, that is better for thicker material. What do you have for a tig setup?

Gas-wise I have 80/20 mix for steel... as for the actual TIG its nothing special but only DC,
