The MagnaFlow 15670 is a Touring Series cat-back exhaust for the Volkswagen Golf III, replacing the factory system from the catalytic converter rearward. The manufacturer builds it from 409 stainless steel with mandrel-bent tubing and says extensive 3D scanning during development produced an OEM-like, direct-fit design. The manufacturer states the system adds horsepower and torque and tunes the exterior note for a more comfortable cabin sound. The limited lifetime construction warranty supports the price for buyers who want stainless construction and a direct-fit system rather than a budget kit. Search terms this part fits include Golf MK3 VR6 cat-back, 2.0 8V stainless cat-back, and 409 stainless mandrel bend exhaust.
The manufacturer lists fitment for the 1993-1998 Golf 2.0L and the 1995-1999 Golf 2.8L VR6, though other listings show different year ranges, so confirm your engine and model year before ordering. The clamp-on inlet and two 3-inch tips are the main visible differences from a stock exhaust. Owners on user forums report that one tailpipe can end up sitting farther out than the other after installation. They generally correct this by loosening the hangers and sliding the muffler assembly to square the tips before final tightening.
The manufacturer lists the 2.0L for 1993-1998 and the 2.8L for 1995-1999. Other listings show different year ranges, so check your engine and model year against the manufacturer before ordering.
The manufacturer's listing says neither a mounting bracket nor a gasket is included. The manufacturer also states the kit includes the hardware needed for a do-it-yourself installation, so confirm the exact hardware list with the manufacturer before ordering.
Owners on user forums report this after installation and say adjusting the hangers and sliding the muffler assembly generally corrects it. Details vary between installs, so check tip alignment before final torque.
The manufacturer describes this as a bolt-on installation that requires basic automotive knowledge and recommends professional installation. MagnaFlow's install sheets for its other exhaust systems advise soaking rusty fasteners and hangers with penetrating lubricant, reusing the original rubber insulators, and leaving clamps loose until the system is aligned. Those sheets cover other part numbers, so check the sheet for 15670 before starting. Common gotchas are seating the welded hangers properly in the OEM insulators and keeping clearance from the frame and bodywork before tightening.
