Do I need new exhaust piping to connect these headers?

These headers bolt directly to your engine. Your existing exhaust system (downpipe, muffler, etc.) will connect at the collector outlet — verify your current piping diameter matches before ordering.

Will these headers bolt straight to my engine without modifications?

They mount at factory engine bay points. Clearance with headers, engine bay components, and steering linkage varies — have your vehicle ready for a test-fit before committing to installation.

What about gaskets and fasteners?

Headers ship as an assembly only. You'll need new header gaskets and fasteners rated for your engine — these are sold separately and should be sourced based on your specific block and mounting configuration.
