hey guys.  ok, i feel that i have an exhaust leak & im pretty sure its coming from the rear end of my cat.  so i got a new gasket & am going to replace the old one(which i hope will correct the problem).  now what i wanna know is, is it as easy as i think it is?  unscrew bolts, remove old gasket, put in new one, & re-tighten bolts?  or am i missing something?  also, do i still have to use gasket sealer even though im putting in a brand-new gasket?  any help is appreciated,thanks!
