I can honestly say that the Milltek is the most superior exhaust in fitment, sound quality, and performance I've seen.
Following in the footsteps of the successful manifolds for the
Mk5 Golf R32, Milltek Sport have now completed development on stainless steel free-flow manifolds for the Mk4 Golf R32. The manifolds have been designed to work in conjunction with the hugely popular sports catalysts and cat-back exhaust system. Their primary purpose is to improve exhaust gas flow directly from the engine, this gives more power, better driveability, and no loss of torque...and that's not even mentioning the sound quality (see the video clips below)!
The Milltek Mk5 full performance exhaust system produced a massive gain of 13bhp and 20lbs/ft of torque - without a remap! Exceptionally good results for this engine!
