MK4 Golf / GTI Turbo Backs & Full Systems (99-05)

By replacing the restrictive OEM system on your MK4, air flow is increased and exhaust gas temperatures (EGT) are lowered, resulting in more power and torque. Browse our selection of performance exhaust systems from brands like Billy Boat and more.
