  One of the most noticeable negative aspects of internal combustion engines is noise. With the growing number of cars on the road, governments attempted to limit this noise by insisting on muffler installation . Put most simply, a muffler is any device that reduces sound. In the context of automobiles, this sound reduction is done by catching the exhaust of the engine and routing it through a series of baffles. These baffles force the sound waves to collide and cancel each other out. While this noise reduction is necessary, it comes at a price – engine efficiency. The process of catching and forcing the exhaust through sound baffles slows it down so that the exhaust behind it builds up as back pressure. This back pressure works through the entire system and creates a bottleneck. The entire performance automobile industry has been working for years to eliminate this problem while still retaining the noise deadening effect. The first, and to date most effective, measure has been the...

  Vintage cars are literally to-die-for. Not only are they a living piece of history that you can brag about without fear or shame, they are also a testament to craftsmanship that has all but faded into the hinterlands of memory.  Vintage cars  are not only great collector’s pieces they are eye candy that you can boast about, as you ride it in real time. However, most vintage cars tend to ‘pale’ in comparison to modern vehicles, not in regards to craftsmanship, but in those little aspects that make modern cars a marvel – electronics. Such things can be as simple as built-in GPS, a sound-system, air-conditioning, advanced car security, power output management systems and the like, all of which are absent or lacking in vintage vehicles. But you needn’t be stuck with a vintage vehicle as-is, because the rewards of  customizing your vintage vehicles  are nothing short of life-changing, not only for you, but for your treasured vehicle. Why customize? Customizing your...

Back in the day, the earliest exhaust systems were dumb metal linkages. Sure, the welded pipes worked efficiently. They rid the engine of waste gasses well enough, but there was no emissions control in the system. Today’s exhaust pipes are smart by design. They incorporate a special oxygen monitor, an O2 sensor that monitors and controls engine emissions. It’s all about feedback, but what is this control loop altering? Fuel Mixture Oxygen sensors (O2) are typically installed in the exhaust manifold . They monitor oxygen because this is the atmospheric gas that mixes with your fuel to generate combustion. Engines are finely tuned so that the bulk of the fuel is burnt and no waste remains, but if the burn ratio is oxygen rich, well, this heavy mix will induce waste. Similarly, a lean oxygen-to-fuel mix also produces pollution. The O2 sensors detect this misbalance and send the data to your engine’s computer, which is when the check engine light starts to flash its warning. ...

It’s not always easy to discern the differences between mufflers and exhaust systems . That’s probably because some of us are guilty of liberally swapping the terms whenever it suits us, but this practice needs to stop. End that confusion by remembering a muffler is a chamber for “muffling” the noise generated by the exhaust system. Then, drive that point home by knowing the full architecture of a top-of-the-line exhaust system. What is A Muffler? This chamber lives as an inline component within the exhaust system. It’s generally located at the end of the pipes, just before the tailpipe. Now, there might be a tailpipe extension down there, perhaps a couple of mechanical clamps supporting the additional pipe section, but this noise attenuator is still located at the rear end of the piping. It’s generally filled with chambers and perforated tubes. Functionally, this little devil should absorb sounds so that the car runs quietly. Realistically, at least on performance vehicles, th...

The diesel versus gas engine debate has been around forever. Both fuel sources require different types of engines because their fuel sources expend energy via two opposing methods. Meanwhile, turbochargers and fuel injection systems add complexity to the mechanical innards in the diesel compartment. These design factors explain engine performance differences and the need to roll up to the right pumps, but how do they affect  exhaust system differences ? In point of fact, are there any differences between them? Compression Contrary Designs Engine Compression characteristics are pushed to the limit in diesel applications. Temperatures rise higher, internal pressures are elevated, and gas velocities are accelerated. Conversely, more torque is generated by a diesel engine than a comparable gas model, so these lower RPMs will produce as much power as a fast-cycling gas engine. Supplemented With Turbocharger Kits The spark-less cylinders in a diesel engine rely on a compr...

Vehicle engineers have established broad exit channels for car engine exhaust , but there’s always room for improvement. A header back exhaust system reinforces this maxim by pulling up the proverbial bootstraps of the aftermarket craftsman and extending the factory replacement process all the way to the engine manifold. For a portrayal of how this process makes headway, read on and embrace our tailpipe-to-engine rundown. What is a Header Back Exhaust System? Power-robbing exhaust components go straight out the window when the kit extends all the way to the engine header. Everything, and we mean everything, is swapped out during this expansive upgrade. In doing so, the diameter of the exhaust pipework is increased, as is any intermediate linkages and crossover pipes. Finally, the muffler and catalytic converter can optionally be ousted in favour of improved chambers, but this latter rationale is subject to a manufacturer’s interpretation of the kit. Removing System Bottle...
