How Much Horsepower and Torque Can be Gained From a MagnaFlow Exhaust System on a 2012 Frontier

Question:

Im curious what gains in HP and Torque can be expected with this system. I have a 2012 Frontier SV V6, I have already installed a Volant cold air intake. With this intake I have gained power but sounds and feels like its choking up for a second under hard acceleration. My guess is that I dont have the exhaust to move what intake can deliver..? Any specs would be helpful to set my goals.

I spoke to my representative at Magnaflow and they stated that you can typically expect an increase in horsepower and torque up to 8HP and 10TQ respectively with the MagnaFlow Exhaust System part # MF15580 installed on your 2012 Nissan Frontier. The choking upon accelerating will not be caused by the Volant Cold Air Intake nor fixed by installing the Magnaflow exhaust system. This is likely an issue with your throttle body or catalytic converter.

A cold air intake paired with an exhaust system will allow your engine to breath better which in turn will give you better performance. However, the engine will only take-in/release as much air as it needs. The use of either of these products will not increase this. The only way to increase how much air the engine moves would involve installing a set of aftermarket heads with a larger intake port or porting your stock heads to allow for more airflow.
