Will the Bully Round Resonated Bolt-On Exhaust Tip Increase Horsepower


I just purchased the bully round exhaust tip, will that increase horsepower for my car?


Expert Reply:

The Bully Round Resonated Bolt-on Exhaust Tip part # PM-5104 will slightly change the exhaust note (more crackly) of your 2014 Mazda 3 but it will not increase horsepower/torque. In order to increase horsepower/torque you will need to obtain a cat-back exhaust system, MagnaFlow Cat-Back Exhaust System part # MF15297 for hatchback or part # MF15294 for sedan models which does so by reducing restrictions allowing the engine to breath better. According to MagnaFlow, the above systems will provide increase in horsepower and torque up to 10HP and 10TQ. However, the most notable differences will be in throttle response and the improved torque curve.
