Problems with header Install

[50canuck]

Driver side header went in OK, by attaching header to heads first, then doing the connection to cat pipe. but pass, side not same story, when attaching header first, collector doesn,t line up to good with cat pipe. Should I do cat to collector first, leave bolts a little loose then do header to heads? The flange bolts line up pretty good. Its a pain doing it without hoist.
thanks

NO !!!!!!!!!!
in case you didn't hear that....NOOOOOOOOOO!

they will leak for sure, bolt tight to the head, then collector to the h-pipe....

do whatever you gotta do to get it close, i use my feet, did you completely remove the entire exhaust?

cuz if you didn't you'll fight the mufflers too , trying to get h-pipe to header

Bolt both headers to the heads before you try putting the h-pipe on EITHER collector.
