How to increase car performance?

So-called for its placement behind your catalytic converter, a cat-back exhaust system replaces your restrictive stock muffler and factory exhaust pipe. Paired with an aftermarket high-flow catalytic converter, this superior system increases both torque and airflow to improve horsepower. Look for systems with large-diameter, mandrel-bent pipes to see the most impressive gains. Cat-back systems also feature straight-flow mufflers to further contribute to the freedom of airflow through the exhausts for even more power.

6. Performance Chips & Programmers

The computer that controls your engine is factory-programmed to comply with certain emissions and fuel octane requirements that leave a lot of performance capabilities on the table. By utilizing power programmers and performance chips to adjust your vehicle’s settings – like fuel-to-air ratio, turbo boost and ignition timing advance – you can easily increase engine power and torque. Performance software is easy to use and usually features plug-n-play installation that connects directly to your OBD-II port and even comes programmed with pre-made or customizable tunes.

7. Forced Induction (Superchargers & Turbochargers)

Forced induction systems, like a supercharger or turbocharger, compress the air flowing into your engine and offer the greatest performance increase. It’s not uncommon to increase horsepower and torque by over 50% with the aid of forced induction. By adding more air, the engine can also mix in more fuel, so a charged engine produces more power overall, which significantly improves acceleration. While a supercharger’s powered by a belt that connects directly to the engine, a turbocharger gets its power from the exhaust system. Turbochargers are considered more efficient since they use “wasted” energy from the exhaust stream as their power source, but by nature present a greater delay (or turbo lag) until you feel power. Superchargers, on the other hand, offer almost instant power when you step on the gas and are usually easier to install.
