Finished in Panther Black Metallic over Onyx and Red leather, the car is powered by a 6.2-liter V8 linked with a six-speed automatic transmission and a limited-slip differential. Purchased by its current owner in February 2022, this G8 GXP is now offered with a reproduction window sticker, service manuals, a car cover, the removed exhaust system, a spare set of wheels, and a Michigan title. A catalytic converter is an exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves. Whether you’re accelerating up a highway on ramp or passing slower traffic, improved acceleration lets you get up to speed more quickly. Gain horsepower, increase torque, and give your truck a more aggressive exhaust note with a new exhaust system.
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.
Next we have the option we refer to as the Cat-back system (sometimes also known as "with Front Pipe" exhaust). One of the most noticeable changes after installing a cat-back exhaust system is the sound. The exhaust note becomes deeper and more pronounced, giving your vehicle a more aggressive tone. The specific sound varies depending on the muffler and pipe design, allowing drivers to choose a system that matches their preference for loudness and pitch.
By running pipes from the catalytic converter to the muffler and from the muffler to the exhaust tip, cat back exhaust systems improve exhaust gas flow, providing small performance boosts. However, your performance gains may be limited if your catalytic converter restricts gas flow, as a catback exhaust system is installed ‘downstream’ of the converter. Header-back systems are increasingly rare, namely because of modern emissions systems. Since removing your vehicle’s factory emissions components is highly illegal, the previous two options are more common. However, 240sx header-back systems are still available for some older, pre-emissions applications. In these cases, header-back systems offer more performance and volume than cat-back or axle-back systems
