Cometic - Best rb25det exhaust manifold gasket?

[opponheimer]

Made 440hp on the dyno the other night thinking my exhaust had a leak in it, turns out it was half my exhaust manifold gasket was blown, it was the cheap felt kind anyway.

Is this a good gasket or should i just get stock? Price is about the same: Cometic MLS Multi Layer Steel Exhaust Manifold Gasket RB20DET RB25DET (http://www.frsport.com/Cometic-MLS-Multi-Layer-Steel-Exhaust-Manifold-Gasket-RB20DET-RB25DET_p_12518.html)



Thanks... the shop is being lazy not sending me dyno charts but the car rips.

it made

340hp 299tq on 10psi
392hp 335tq on 15psi
438hp 370tq on 20psi

If i could raise rev. limit the car would make way more HP because it kept building hardcore. I'm starting to not regret getting an rb25det
