I have a Mk3 Golf with the 2.0 ABA motor. Recently, the original center-resonator rotted out and as such, I am now on the lookout for a cat-back system. Unfortunately, I have been having a terrible time finding the correct resonator/over-the-axle section.
I have tried several Walker and Bosal OEM replacement exhausts and the fit is terrible. In all cases, the resonator box interfered with the heat-shield and e-brake cable for the driver's side rear wheel. Further, and this is where I am having a problem, the hanger for my original resonator is just in front of the resonator and on top of the inlet pipe to the resonator in the shape of a hook that is parallel to the direction of travel of the car. Most of the aftermarket exhausts show the hanger mounted in front of the resonator but underneath the inlet pipe in the shape of a straight bar that is parallel to the road and perpendicular to the direction of travel of the car.
Magnaflow lists 15670 for the Mk3 (1993-1998) and 15648 for 1999-2006 Golf so I assume that exhaust is for the mk4. I called Magnaflow and the guy told me to go see my VW dealer to help me figure out what kind of car I have! No help at all.
My Golf is awesome and it deserves a nice exhaust. It only has 83k miles on it, doesn't burn a drop of oil, runs on lowered suspension with all urethane bushings, mk4 front clip, Bonrath grille - it's cool!
I am hoping somebody knows what cat-back exhausts actually fit a 99 mk3 before I have to go get something custom made.
