2007 Mazda Speed 6 - Power Pages

Pros
The mandrel-bent, 100% stainless construction, and clean welds speak to the high-quality construction of this product. A pleasing deep and robust tone (sans any drone at highway speeds) that manages to keep the decibels just slightly above factory levels was a definite plus for legality.

Cons
Tips are round, yet the exhaust ports in the rear valence are oval. Despite this minor oversight, cosmetically, it looks fantastic. Tone may be too understated for those looking for a more aggressive sound.

Parts
Dual mufflers with attached rear section piping, T-pipe, front pipe assembly, band clamps, and hardware

Tools
14mm wrench, socket, ratchet and extension, hanger tool, PB Blaster, WD-40

Installation Time
90 minutes

Notes
Proper installation takes quite a bit of finessing, and copious amounts of WD-40 to perfectly center the tips in the rear valence ports. However, this step is critical as contact between the metal and plastic will cause avoidable damage to the bumper.

Pros
The provided software allows for easy D.I.Y. tuning, in-depth data logging and on-the-fly map swapping, using a PC or toggle switches. The standback controller uses high-resolution 30x30 tables and stand-alone-like control over certain parameters. With simple installation and removal, using a plug-and-play harness also offers an optional integrated water/methanol controller. Manufacturer calibrated maps are available for CP-E bolt-ons.

Cons
Its D.I.Y. tuning is a feature that may prove dangerous for owners who believe they are "semi-pro" tuners, being this is relatively new to this market, and local tuners may not be familiar all its features. However, the software interface and tools should be easy for any professional tuner to utilize.

Parts
Engine Controller, software, harnesses, firewire

Tools
Laptop, software, qualified CP-E tuner

ECU Time
30 minutes

Notes
Once this unit was installed and calibrated, this engine's true potential began to materialize. Not only did the Standback improve and smooth low-end response, we were also able to finally extract usable power from the top end. If you're wondering what exactly a "Standback" is, think of it as a stand-alone/piggyback hybrid. Unlike a piggyback, this doesn't simply modify signals from the factory ECU. Instead, like a stand-alone it directly controls boost, spark and fuel delivery functions, while allowing the stock ECU to retain control over other parameters, eliminating some of the pitfalls of a piggyback and cost of traditional stand-alone devices.

Conclusion
With this type of build, gains of 46 hp and 36 lb-ft of torque alone would give cause for celebration. However, beyond just peak numbers you'll see a substantial increase in power output throughout the entire powerband. This isn't just paper performance either, it now pulls much harder and with confidence it previously lacked. Given the relatively low cost per hp gained and exceptional improvement in real world performance, we've transformed this mannerly sedan into a true sleeper. EVOs beware.
