Fremuff Performance Exhausts
332 J. Abad Santos Street, San Juan
When Freddy Mabazza started making mufflers in 1996, he named his shop with his own name 'Freddy's Mufflers'. Later opting for a more appealing name for young enthusiasts, he combined Freddy and the word 'muffler' together and came up with FREMUFF. Since then, FREMUFF has been one of the leading names in sports mufflers and performance headers.
