RR RACING QUAD TIP UPGRADE FOR BORLA EXHAUST SYSTEM FOR LEXUS IS-F
Dual Magnaflow wide open mufflers with quad 3.5_„? exhaust tips, slightly louder and deeper than standard Borla. This upgrade option retains the large Borla resonator and replaces Borla mufflers with dual Magnaflow mufflers and quad tips. Borla is a great exhaust, but with this upgrade your back will look much better with the large aggressive oval quad tips and will sound better too! We feel that Magnaflow offers great mufflers at an affordable price -- we tested these mufflers off and on the track for over six months.
