These megaphones are 24" in length and come with cookie cutter end pipes that made the Porsche factory team famous! They are designed to fit "European Racing Headers" 911 Headers right at the end of the collector flange. These megaphones are by far the most popular megaphones that we sell. Megaphones come with all applicable gaskets, nuts, bolts and washers needed. Megaphones are sold in pairs only. GT Racing also recommends buying the megaphone bracket assembly (GT Racing Part #911-BA). It is very important to support the megaphones with the bracket assembly.
