Replaced drivers side header (crack between 3 & 5) with Kirbans Ta performance header. Old header flange was not round & connection to crossover pipe leaked. Removed crossover, brought to muffler shop and made round again on drivers side only. Used high temp rtv silicone on both sides of crossover, tightened evenly back & forth on both sides & left it for 24 hours. Initally no leak but after getting into boost a few times drivers side leaking again. I searched and saw a Fel-Pro flange gasket # 23624 as a possible fix. The crossover pipe is not cracked & in good shape. Is it worth trying the flange gasket with some rtv or just get Kirbans 2 piece crossover and be done with it. It kind of sucks that before I just had a slight leak from the header crack (ticking sound) & now a crappy exhaust leak which sounds much worse.
