Proflow Exhaust Manifold Stud Kit, Titanium, For Nissan, TB45/TB48, Patrol, M10x Gauges Part Number : AF556-16SPart Number : Manufactured from Ti 6Al 4V Grade 5 titanium, Proflow's titanium exhaust manifold stud kits for most popular engines are a perfect upgrade over your factory studs when chasing some big power! It is common for the factory manifold studs to come loose and fail over time due to the heat cycles produced by the cylinder head, and this can become a bigger issue especially when you are using aftermarket bolt ons such as upgraded turbochargers.
