Will these fit without removing the engine?

Long tube headers typically require engine bay access from below. Check your available workspace before ordering — some installations benefit from dropping the K-member or using a lift.

Do I need a new exhaust system to run these headers?

Your existing mid-pipe and rear exhaust will bolt to the collector outlet, but you may want to verify the connection diameter matches. Some owners upgrade to a catback system at the same time for better flow continuity.

What prep work is needed before installation?

Clean the mounting surface on the cylinder head and intake manifold area to ensure a clean gasket seal. Have gaskets ready and torque to manufacturer spec — refer to your service manual for exact values.
