If you are switching to an after market exhaust manifold on your 1JZ or 2JZ engine, then many of the manifolds require a shortened exhaust stud to provide proper fitment.

We have custom sourced genuine Toyota parts that do the job, and have included the correct nut 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.

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

Need the reverse Torx socket in 3/8ths drive to remove the old ones and install the new? We can get that too!

The studs protrude 22mm (7/8") from the head flange when installed. In the pictures for representation, the longer, rusted studs are the factory 2JZGTE ones.
