XYZ the ultimate Y-pipe! For the best sound, power and versatility, look no further. The Motordyne XYZ-Pipe is a high performance Y-pipe unlike any other.

In its development phase many different merge distances and merge angles were dyno tested. With a range of tested Y merge distances ranging from very close to very far from the engine and with merge angles from high to low, it was found that engine performance was degraded if the Y merge point was too close or too far from the engine or if the merge angle was to high or too low. The Motordyne XYZ pipe merges the exhaust gasses at the optimum distance and angle.

With several data points analyzed a curve was generated and it showed that when the merge angle was correct, the optimum ''Y-pipe'' length peaked at 16in. A 16in long Y-pipe would normally be too short of a Y-pipe to fit in the stock location so an extension was added behind it to connect it with the midpipe flange. This extension is what created a new opportunity to incorporate a resonator to improve sound quality. It also opened up the opportunity for an add on catalytic converter. Both of these options become even more advantageous when test pipes are used.
By incorporating a resonator or even a catalytic converter in the XYZ-pipe it allows you to take advantage of the higher power gains available with test pipes without sacrificing the sound quality, power or exhaust smell. And all the extensions (or modules) can be easily and quickly changed out with the supplied V-band clamp.
