Does this header come with gaskets and bolts?

The header assembly is included. Verify your bolt kit and gasket compatibility before installation — some buyers source OEM gaskets separately to ensure a sealed fit at the manifold flange.

Will I need to modify my exhaust system to fit this?

This header uses the factory manifold mounting points, so no engine-bay modifications are needed. Your downstream exhaust (cat, resonator, muffler) will need to be checked for clearance and proper fitment to the collector outlet.

Can I install this myself, or do I need a shop?

Removal and installation are straightforward with basic hand tools and a jack. Give yourself 2–3 hours. The biggest hassle is usually accessing the bolts in tight spaces and letting the engine cool completely before you start work.
