2003-2009 Toyota 4Runner Stock Replacement Exhaust

Sometimes the exhaust doesn't need to be louder or more powerful — it just needs to not be rusted, cracked, or leaking onto the heat shield anymore. That's where 2003-2009 Toyota 4Runner Stock Replacement Exhaust comes in, getting the fourth-gen back to where it should be without changing its character.

 

OEM-spec hangers and flanges are worth insisting on here since a replacement that uses undersized hardware ends up with the same rattles and fitment issues as the part it replaced. Aluminized steel is fine for most climates but owners in heavy-salt regions should look for stainless replacement sections since the fourth-gen platform is at an age where corrosion is already part of the story.
