Frequently Asked Questions (FAQs)

1. Can I use bolts instead of studs for exhaust manifold?

I would say yes, as long as you can tighten it down the same torque that what was on there Originally. I see no reason why you can't use a bolt or a bolt as a stud.

2. What is recommend to use on the threads of exhaust manifold bolts or studs?

If you are reusing exhaust manifold bolts (which we don't recommend), apply a metal fortified anti-seize to your manifold bolts. If you've just removed the broken bolts and ready to complete the repair, chase the threads clean and use fresh OEM bolts for best results.

3. What do exhaust studs do?

Every engine has an exhaust manifold that helps to gasses back out from the exhaust valves through the exhaust system. It is mainly connected or bolted with studs. These studs break inside the head or flush.

4. How do exhaust spring bolts work?

It's there to prevent vibrations. They keep the exhaust sealed but allows the joints to flex under engine movement.
