my fmf fatty pipe kit come look need help

I had got a fmf off from ebay without the flange.i called fmf an the flange cost me $35.00 if i remember.
 
We cut the flange off the stock pipe and put it on the fmf....hooked the spring into the flange...worked perfect!

That's what i did at first it made the fmf out about a 1/2 in. from the cylinder which gave it a ton of bottom end when i got the flange it made a night an day:)
 
I had to grind my stock flange an cut it from the stocker to fit it worked a lot better than stock pipe but that 1/2 i got out of it was worth buying the fmf flange.
