As for the difference in cost.

1) Its made in the Los Angeles, USA.
2) Its taken to a much higher level of polishing. Its not just quickly buffed. They go through 4 stages of finishing to achieve a deep polish.
3) Its taken to a much higher level of TIG welding.
4) It uses triple layered flex lines for flexibility without turbulence or whistling.
5) It uses V-band flanges and clamps.
6) It uses predominantly dual 3" Stainless Steel 304 tubing (for greater power capacity in the 8-15 PSI boost applications).
7) It is modular so it can have additional resonators or HFC's built into the mid pipes.
8) It can easily be converted to a full dual 3" exhaust for very high HP capacity.
9) It comes with 2 different pairs of adjustable/removable titanium and Stainless tips for different looks.

No other 370Z exhaust can do all this.

The above are real cost drivers for features not seen in any other exhaust.

The Shockwave))) E370 is the best exhaust available to the 370Z.
