Home made SFC's

I've been searching for hours and hours, please dont send me searching again.

I at this point have had the car go quick enough(low 13's) without SFC's or the rollcage i have(jegster) installed yet.

I have been looking at the MAC SFC's and well, their cheap, and it seems people like them.

Other manufacturers as well.

They seem easy enough to make, although i do not weld, tho i hope to learn very soon now.

What points have to be connected, and whats the best way to go about doing it without restricting exhaust routing?

I see LCA's are the majority location in the rear.

Some people connect directly to the front subframe while cutting off the exhaust. I wish to not do this.

Anyone have a set of their homemades running stock exhaust routing?

Deatiled and labeled pictures are requested, i have been searching and searching and it seems the best sources have since been deleted, or something else.

Are the $150 MAc's worth it as compared to making homemade ones?

If TGO will let me post it- here is my plans for custom panhard bar and SFC's im making as we speak.. i should have them about done tomorrow afternoon hopefully.. just open it up in paint or something.. the Right side drawing there is lookin at it from the side if you take off that front angled piece i drew in w/ pencil..

It is set to be raised on top of the other one and then triangles welded in the corners to create a "Z" with the 33" piece and the 10" piece then the 15" piece welds at an angle to that. I was going to heat the 15 inch piece up w/ the torch and bend it a bit so it will go over an exhaust - b'c my car currently just has a Y pipe... all the measurements are listed for you there.. It cost me $76 for the metal not the Estimated $115 or whatever it says.. The panhard bar is actually 41" long- i learned that -.. didnt measure twice and cut once.. i measured once and cut twice....glad i had extra metal..

Hope this helps!!!!
