This exhaust is going to sound the deepest and give you some nice pops and bangs, while also giving you real world WHP and TQ gains. We’ve seen as much as +12 WHP when we tested our turbo-back for the 2022+ Honda Civic! For this version, we do recommend a tune and a device like a Ktuner V2 or Hondata Flashpro to take full advantage. Since the OEM catalyst is replaced with the downpipe, the Turbo-back system is sold for Race Use Only. A cat-back exhaust system replaces the stock exhaust components from the catalytic converter back to the exhaust tips.

The amount of horsepower gained from installing a cat-back exhaust system varies by vehicle and the system’s design. However, when combined with other performance enhancements, the gains can be more significant. The primary goal of a cat-back exhaust is to reduce back pressure, allowing your engine to breathe better and operate more efficiently. The factory exhausts come in mandrel bent tubes made of stainless steel or aluminized steel. Besides offering longer durability, the construction also ensures there’s free flow of gases. To improve this, you can opt to replace some parts of the exhaust system using aftermarket performance exhaust systems.

In 2010, most light-duty diesel manufacturers in the U.S. added catalytic systems to their vehicles to meet federal emissions requirements.
