haha, no, that couldn't be. well, i won't tell anyone..

but again agreeing with justin, i've seen many people post about their AWE/ASP/VAST manifolds cracking(although some have run them for tens of thousands of miles with no problems). but haven't ever seen anyone with OEM manifolds crack, stock/stg1/2/ and 3+, they're just the way to go.

but i would ceramic coat them while the engine's off, it's just a little bit more work, but i would think worth it

 

worst case scenario the coating chips off and youre back with regular *** oem manifolds. there would be negligable increase in power with ASP and AWE and maybe even these but if they start leaking on you...no good.
