TTI/Eddy Sealing Problems?

340s,when i first ran my tti's i used the gaskets they supply..i'll tell ya' i had zero leaks with them...might be worth a try..

I already fixed the problem by making the bead around the flange wider. Its not a gasket problem, there is no metal to pinch the gasket, any gasket, because of the way the flange's bead lines up with the exhaust port.
