To create this system, Milltek technicians have opted to use full-bore 76mm / 3-inch pipework and a twin compact rear silencer for effortless gas flow. However, Milltek understand that most owners will want to use their cars every day, and don't want a constant and intrusive booming from their exhaust. As a result, after painstaking road testing, they found that a volume-specific centre silencer, also known as a resonator, was needed to keep unwanted noise when cruising under control.
Milltek's ultimate GTi exhaust is currently in testing with a well-known member of the Mk5 Golf GTi forum and, although very busy at the moment, he's managed to give us his first impressions after using it for the last 7 days:
"In very simple terms I am 100% over the moon with the system, everything we discussed about performance, sound quality and looks have all exceeded my expectations of the system. It has even passed the test for the other half driving the car without complaining :-)"
