Default triple gasketing?

Im almost done my custom e cutout set up (custom in the sense that im fitting a 3.5" QTP on my 3" cutout. It is currently double gasketed with clearanced gaskets to give the valve time to open before having to fit in the pipe but it just barely catches. So i was thinking 1 or two more gaskets will do the trick. Will running 3 or 4 gaskets cause leaking problems or anything else?

If you can get a cutout to seal up, you've done something. Those gaskets suck. You could try some high $ copper gaskets if you're really worried about it sealing all the way.

The dead soft aluminum seem to work pretty good. Percys and Flowtech manufacture them. I am sure that one of the sponsors carries something like that.

Yea, I plan on trying some of them when I put my headers on the boat. Not like I'll be able to hear an exhaust leak anyway

Yeah, they work about 95% leak free. Good choice.

i need to use more then one gasket.. the gaskets are used to space the QTP a little off of the cutout. Two hasnt spaced it far enough but it is really close
