It's been 18 long years, since the #Supersprint stainless #exhaust for the #Volkswagen 2002-2004 #GolfR32 has been introduced, becoming an immediate sales hit.

Among the Golf community, worldwide, the R32 had become the real GTI in the gen. 4 Golf range, making more performance and better sound than the four cyl. GTI 1.8 Turbo.
However, its standard exhaust was far from being the perfect system for the VR6 engine, as it proved to be restrictive, overweight, nice-sounding but still too quiet.
We at Supersprint spent long, hard working days, designing a totally new exhaust from the ground up, in order to overcome these negatives.
While everyone in the exhaust business went the easy way, and settled on offering the cat-back part of the exhaust only, for pure cosmetics, and more noise, we had a totally different approach, focusing on the restrictive, power-robbing areas of the exhaust system instead.
Putting lame efforts has never been in our DNA; when we design new exhausts, we always aim at getting the best.
More peak Hp, but most important, more torque in the midrange; now that was our goal.
We have changed everything in the layout of the stock exhaust, from all the way up on the engine head, by designing longer primaries with specific flanges to match the exhaust ports, to enlarging piping diameter on each individual section, to building a straight-thru, single-perforated core, tuned muffler.
Hence the Supersprint tubular headers, with their HJS Motorsport, twin metallic cats were born, complemented by our free-flowing rear muffler and mid resonater.
Tested back-to-back against the stock system, this new Supersprint full exhaust made huge gains, from the low rpm
range to redline, also guaranteeing a throaty, drone-free, powerful sound.
The results were clear, as the maximum increase was + 20 Hp, + 30 Nm torque, made throughout specific, wide areas of the powerband.
Technically speaking, the most interesting guideline drawn by our R&D Team was, not going overboard with piping size, as our in-house dyno testing, done with exhaust gas backpressure monitoring, made it clear that this particular VR6 powerplant (in its stock form) performs to its best potential with firm, 65mm tubing.
Equally important, we carefully routed the pipes well within the tight confines of the 4-Motion drivetrain, always ensuring a proper clearance.
The final fitment of this Supersprint exhaust proved nothing less than perfect.
Later on, we also introduced a larger size, 70mm specific exhaust, recommended for more radical tunes and supercharging conversions.
