Pros
DC Sports exhaust systems are CNC mandrel bent from T304 stainless steel and features a polished, barrel-style canister that delivers an aggressive growl when mashing on the accelerator through polished four-inch, straight-cut exhaust tips.

Cons
Removal of the factory exhaust requires plenty of time and patience. Ask for assistance when installing the new exhaust to help speed up the process.

Notes
We were pleasantly surprised with the nice, deep exhaust pitch at a modestly quiet decibel level. Dyno testing the exhaust revealed an increase in power and torque throughout the power band, with a peak gain of 10.1 hp and 4.6 lb-ft torque. We saw a healthy gain in the mid-range and top-end, from 4,000 rpm to 6,400 rpm, where the 350Z posted an improvement of 11 hp and 8 lb-ft of torque.

Conclusion
What began with a baseline dyno run of 232.7 hp and 225.1lb-ft of torque was quickly revamped with a respectable improvement of 16.7 hp and 8 lb-ft of torque, using three simple bolt-on products. With a plethora of aftermarket upgrades available for the 350Z, including aftermarket fuel management systems and free-flowing headers, we foresee this Z smoking its tires in no time.
