OEM 2 piece is far superior to one piece ceramic.
I run stock seals at 1.8bar boost pressure and high power (Ferrari F40 beating , ZR1 Vette beating, Pagani Zonda beating performance). And its my daily driver 
Stock Mazda apex seal is best, worked good for many many people over the years.... >

My 478rwhp daily driver from 1997 to 2002, stock Mazda 2mm apex seals, reliable as, you will also see a customer engine set up of 550rwhp, again stock std Mazda apex seals............ when he did experiment with tuning changes he detonated that engine and the stock Mazda apex seal just cracked, a ceramic by comparison would have shattered and destroyed the whole engine.
Stock Mazda 2mm apex seals can take HUGE amounts of power and boost, and best of all they are very tough, but also very durable at the same time, there is nothing else you can buy that fits all those criteria.
