Exhaust system modifications produce readily accessible engine efficiency gains. In essence, wide diameter pipes and bolt-on kits act as a gateway to increased performance. One moment, though, these alterations only work properly if the car’s engine capacity is matched with the right exhaust system . Otherwise, you reach a point of diminishing returns where performance gains flat line. Here are some handy tips for avoiding this horsepower plateau. Squeeze the Engine for Extra Horsepower If the exhaust system is open to modification, then so is the engine. Properly establish the engine’s capabilities before turning your attention to the exhaust system. Turbochargers and customized cold-air intake mods involve extra parts, so keep that added expense in mind. If that added expenditure doesn’t ring your bell, then pull the vehicle into your local garage for a full computer tune-up. Basically, push the engine’s power train to its limits before going to work on the breathing ch...

It’s a jaw-dropping prospect, isn’t it? The notion that some unprecedented influence could cause a muffler to explode. Like a blocked pipe in a plumbing system, pressure builds when a fluid-conveying tube is obstructed. Unlike the dirty backup spawned by clogged plumbing, the pressure build-up in the exhaust could make the muffler rupture, so what’s generating the build-up? Is it a blockage, or is it something else? System Deterioration The catalytic converter is loaded with ceramic parts and honeycombed metal plates. Each unit is slightly different due to architectural variances, but metal assemblies and heat-absorbing elements are always part of the inner workings. They catalyze engine fumes while releasing harmless gasses into the tailpipe. Unfortunately, these elements are susceptible to damage. Pushed forward by engine backpressure, the broken innards of a catalytic converter will create a blockage. From here, the pressure goes to work on the muffler seam. In short, i...

Exhaust manifolds are designed to couple each exhaust port of an engine’s cylinder head to a single outlet pipe. Functionally, the steely unit collects ejected waste gasses from the multiple cylinders and ejects them into a single pipe conduit. Viewed from a purely structural viewpoint, the little collector unit is manufactured as a blocky series of aligned ports. Its job is to merge the collected streams of cylinder-burnt gasses, to combine the multiple exhaust outlets into a single channel. Let’s take a closer look. Engine-to-Exhaust System Interface Exhaust manifolds bolt to car engines via heat-resistant gaskets. They’re the compact factory-installed workhorses that convert multiple exhaust outputs into a lone stream so that the unified volume of dirty gas can be expelled down one channel and out through a car’s tailpipe. Unfortunately, that compact profile does not favour free engine respiration. It’s a bit like dropping your head to your chest and trying to breathe freel...

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...

Classic big bikes are purebred beasts. You know the ones we’re talking about, right? We’re talking about the vintage motorcycles that defined an era. Strictly speaking, the fat-engined bikes are outdated, but aftermarket aficionados still have a special place in their hearts for timeless classics. Now, personal bias aside, here are some tips for choosing the best motorcycle exhausts for your classic big bike. Big Bikes Have Never Had It So Good Veteren motorcycles are enjoying something of a revival. Nonetheless, they were built at a time when carbon emissions weren’t an issue. Petrol, gasoline to some of our readers, was just an endless fuel source. Today, things are a little different, so your classic motorcycle must accommodate modern emission guidelines. Say No to Scrapped Parts There are scrapyards and specialist forums out there, but should you be using these resource? Second-hand parts aren’t always the optimal solution, not when they’ve been exposed to the...
