Hm. So they don't have any reference. That's good to know. Thanks.They know their stuff. You wont fool them with an aftermarket exhaust manifold. Everyone knows at this point stock 2zz manifold doesnt fit without lowering or cutting the subframe. They expect to see those subframe mods.
Intake must be OEM or have a CARB number if aftermarket
But yes, I was thinking something different like a certain 1.6L 3-cylinder engine, that if released, would be very limited in production.
