I have the Pacesetter ECO header and a Magnaflow high flow cat that are awaiting install (aka warmer weather).
I wanted to put a 3-bolt flange on the header downpipe and the cat to make bolting this thing up easier.  
Problem is, i don't know where to find a 3 bolt flange that I can have welded to these parts.   Anyone know where I should look?  the header downpipe and cat are both 2.25".  Everything I can find is for 3".
Thanks
