Jetta GLI 16V '87-'89 (2.25" stainless, 55mm cat, Borla muffler): small bumper

With such good high-rpm breathing potential, a small bumper Jetta 16-valve is well-equipped with this exhaust solution. Done right in stainless steel 2.25" mandrel-bent tubing, you can expect easy gains of 7 or 8hp before other mods. The system fits the OEM 50mm catalytic converter outlet and mates to a stainless steel Borla muffler and tail pipe. Two year warranty on tubing and resonator and lifetime warranty on muffler. Clamps and rubber hangars included.
