These muffled megaphones are designed for the track car folks who run on circuits that demand a quiet muffled exhasut system. You can expect a significant sound decrease over the open European Racing Headers systems. This system is a simple bolt on to any Existing European Racing Headers. Many track car folks are using the traditional European Racing Headers "Open" type exhaust and then switching out to this quiet system for the occasional race track that requires a quiet system. This system comes complete with a pair of muffled megaphones including cookie cutter end pipes, bracket assembly, all fasteners and gaskets required.
