  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 simply awesome; they don’t need lots of words to describe their fancy designs like new model cars.

Exhaust shopping plans keeping you up at night? Wondering what exhaust system will be the best suit for your car? Before you dive in for the purchase, tip the scales to your side with 5 4X4 exhaust system facts- You should change the factory exhaust- It's a common perception that the factory set-up parts are perfect for a machine/automobile. This is even true in terms of most appliances and even a lot of automobiles. But, if you own a 4x4 and want to explore the whole potential of your drive- you should switch to aftermarket 4WD exhausts. There are options for single and dual exhaust kits. They both improve the performance, fuel economy, and sound of your vehicle. Double ones are just a bit more difficult to install and have a more customized look. Different material 4x4 exhausts offer different characteristics- You can choose from different materials. The stock exhausts mostly use standard low to mid-grade stainless steel. On the other hand, if you want better quality, you can c...

A glimpse at the different X-Pipe, H-Pipe , and Y-Pipe exhaust system configurations has a novice scratching his head. What’s with all the form factor conventions? Does one perform better than the other? Then, aside from the shapes, there are other differences to scrutinise. Let’s check out the three pipe configurations, their unique qualities, and the reasons for the flow alterations. Exhaust Systems as Characters   There’s not a whole alphabet of welded tubes in the shop, all waiting to be bolted to a car’s underside. No, there’ll never be an A-to-Z of flow shaping pipework. But the X-Pipe , H-Pipe , and Y-Pipe aftermarket product range do have an important place in the exhaust gasses channeling field. Primarily tasked with creating distinctive flow patterns, this is a mid-pipe exhaust stream management system , one that unleashes vehicle horsepower. How do these three pipe types pull off that impressive objective? Crossover Engineered Exhaust Principles   When...

There are essentially two types of people in the market for mufflers . They are looking for different things and how they choose between muffler brands is very different. The first type of muffler buyer is just your average driver. Performance is not an issue and the only real requirement is quiet. For these people, the “best” muffler brands are going to be production brands used for average new cars. To a large extent, it does not matter what brand they choose as modern standard mufflers are relatively equal in performance, price and durability. If they want to shop for a specific brand because it makes them feel that they are doing the right thing, their best bet is heading to auto magazines that review car parts. The second type of muffler buyer with more complicated needs are those looking for a muffler for a performance vehicle. This group of muffler buyers often finds its collective head spinning when faced with choosing between MagnaFlow mufflers , Genie exhau...

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...

The engine in a motorbike is smaller than a car engine, yet its noise profile is louder than its four-wheeled highway cousin. Admittedly, that larger engine is concealed in the car engine compartment, an enclosed alcove that can be soundproofed, while the two-wheeler wears its power plant out in the open. Still, this question begs an answer. Are there exhaust noise differences between cars and motorbikes? Motorcycle Culture Unlike cars, motorbike owners often buy their wheels with the sole intent of putting the bike on steroids. The biker immediately opts for aftermarket pipes. The bike pipes are shorter than a car exhaust system , though, as is the muffler housing . The upshot of this condensed exhaust system is more noise. Essentially, that biker culture and the motorbike’s streamlined form encourage noisy leanings. That bias demands svelte pipework, tighter turns on a slimmer frame, and a near obsessional need to feel that noise vibrate the owners’ fillings. Engine Ar...

A poorly performing catalytic converter isn’t like most other working vehicle systems. If a car fuse blows, an electrical system goes on the blink. It’s the same with the engine because you feel the misfiring cylinders. The engine’s overheating, the car’s stalling out, and there’s a general performance drop off. No, a bad catalytic converter isn’t easy to diagnose, but its symptoms can really hit hard. Hard-hitting Environmental Symptoms What happens when your vehicle’s catalytic converter goes bad? Well, your emissions are moving unprocessed into the atmosphere. When it was functioning properly, the chemical neutralization process converted those emissions into harmless compounds. That’s no longer the case. In the short-term, the car no longer complies with local vehicle emissions standards, as set by a nationally accredited authority. From a long-term perspective, those harmful emissions are contributing to the global warming problems we’re all trying so hard to preven...
