If you are switching to an after market single turbo exhaust manifold on your 1JZ or 2JZ engine, then most of the manifolds require a shortened exhaust stud to provide proper fitment and clearance as well as a compact nut.

We have custom sourced high tensile parts that do the job, and have included the correct nut (plated ) for them as well.

You will receive:
(8, 10, or 12) Exhaust Studs Genuine Toyota
(8, 10, or 12) Nuts for exhaust studs genuine Toyota

We keep a set ready to ship out at all times! Please select the engine you have so we can send the correct quantity.

2JZGE, both VVTi and non, will need 8 nuts and studs
1JZGTE VVTi will need 10 nuts and studs
1JZGTE non-VVTi, 2JZ-GTE, non VVTi, and 2JZ-GTE VVTi will all need 12 nuts and studs
