Do I need to buy new bolts to install this?

You'll want to grab new header bolts separately — factory bolts often seize or strip. Use stainless or high-temp rated fasteners rated for header applications, and torque to your vehicle's service manual spec.

Can I reuse my old exhaust manifold gasket?

No. Always use a fresh gasket when bolting on a new header. Old gaskets compress and won't seal properly, which leads to leaks and heat loss. Pick up a header gasket kit before installation day.

Will this header work with my stock exhaust system?

Yes, it bolts directly to factory flanges. Your existing downpipe and exhaust will connect without modification. If you're upgrading the rest of the system later, this header is a solid first step.
