I have several small exhaust leaks at the head/exhaust manifold and the turbo/down pipe. I took it all apart and discovered some of the surfaces are not flat, so getting that corrected. I know many people who track do not run turbo exhaust gaskets on their Miata with great success so i'm contemplating not using any gaskets this time around. once everything is machined smooth, I am considering using this Cotronics Durabond™ 7032 Stainless Putty product as a "gasket". anyone use this? I have the inconel studs and stage 8 on the turbo/ manafold , which held-up fine with out issue for several seasons but not sure what brand gasket to use or if I should just get rid of the gasket here as well. what about the head/manifold gasket? do people not use a gasket here as well? what about the turbo/downpipe gasket? i'm installing new studs in the turbo and plan to use use jet lock nuts because they seem to be the best mechanical lock nut available in a small formfactor design, which is required by my down-pipe due to clearance issues. any thoughts?
