It's the stuff you've known for decades, this 2.25" exhaust is made with mandrel-bent aluminized tubing and a stainless Magnaflow muffler with 12" resonator. Expect about 7-8 HP gain. Fits Mk2 GTI '87-'92 16V and '90-'92 8V with 55mm catalytic converter. Clamps and rubber hangers included. Two year warranty on tubing and resonator and lifetime warranty on muffler.
For those that require the exhaust a bit quieter consider adding the optional second resonator and/or a venturi.
