Put The Performance In Your Exhaust

Sunday, February 28th, 2010

Through the years, car exhaust systems have played a significant role in helping sporty cars achieve “hot rod” status. These “after market modifications” are heralded by auto enthusiasts everywhere who are seeking to achieve the highest performance levels possible with their cars. You can put the performance back into your vehicle by carefully choosing only the most select performance exhaust parts for your vehicle.

The 1973 movie classic, American Graffiti, underscored what people thought about their cars: we simply love them! Featuring a heralded battle between a souped up ‘32 Ford Coupe and a sporty ‘55 Chevy, the movie projected quintessential American values of fast cars, good looking girls ‘n guys, fast food, and lost love. The cars themselves screamed “pure hotrod” and it was in this tradition American car mania reached its zenith.

Since the muscle car era of the 1950s, 60s, and 70s changes have come about in the automobile industry where most cars can only dream about muscle car status. Environmental and safety regulations coupled with changing tastes have transformed the car market into one dominated by SUVs and boxy compacts. Fortunately, saner heads are prevailing and the newest mix of sporty cars on the road evoke many memories of the muscle car era.

So, how can you help your car achieve hot rod status? Well, unless it is already a sporty model, you have your work cut out for you. Nevertheless, current models including the latest rendition of the Pontiac GTO, the Corvette, Ford’s Mustang, the Dodge Viper, plus select offerings from Cadillac, as well as trucks and SUVs like the Hummer and F-250 are being outfitted with the likes of Borla mufflers and Flowmaster Exhaust systems. Indeed, to help enthusiasts achieve a “sports car feel” technological advances have brought about exhaust systems that have no bothersome resonance or drone, provide increased torque and horsepower, and give off a great performance sound. For their part, Corsa exhaust systems is a proven leader in helping performance exhaust systems become a reality on so many vehicles.

Naturally, when you plan any upgrade to your exhaust system you must take care not to disturb existing emissions control equipment, no matter how tempting that would be. Therefore a “cat-back” exhaust system is your best choice as it would allow you to put large-diameter exhaust pipes and low-restriction performance mufflers into your exhaust system without harming the catalytic converter. With this type of system installed you would be maintaining your car within legal limits while receiving more torque and horsepower, less exhaust backpressure, and a sportier sound.

Yes the original muscle car era is gone, but many of today’s cars can and will achieve muscle car status by carefully outfitting them with high performance exhaust systems and parts.

The Best Out Of An EXHAUSTed System

Saturday, February 27th, 2010

Most of the motorists these days have one thing in common and that is the manifest disregard to some auto parts like the exhaust system. If you are to ask motorists when they inspect the system, you would probably get same reply. The most common occasion when they do such a task is when they are already hearing obvious noise. With that situation, the vehicles are likely to end up in the hands of a franchised exhaust specialist.

Auto exhaust parts experts suggest that motorists should inspect the system whenever it is on the lift for routine service. According to them, it makes perfect sense considering the expense of some of the parts like sensors, mufflers, catalytic converters and others.

Basically, an exhaust system transports burnt gases from the internal combustion engine. Exhaust parts accessories are mainly composed of pipes that vent waste gases. These gases may stream through a turbo charger to boost power, a catalytic converter to diminish air pollution, and a muffler to minimize noise. Clamps as well as bolted and welded connections and hangers hold the system together. So, in inspecting the whole system, motorists should look for snapped bolts, cracked welds, rusted joints, leaks and other deteriorated parts.

Experts added that rubber in the hangers like the doughnut-shaped bands used in hanging pipes should also be inspected. Car aftermarket parts exhaust is always under stress much more than the original equipment hangers. Moreover, it is recommended to select an aftermarket design that is not similarly shaped with the original hanger when replacing the latter. Another consideration is to be certain that installation can be had without twisting or aggravating the stress of the system. There is wide latitude of aftermarket exhausts available in auto parts dealers. Hence, it is definitely possible to hang the system sophisticated aftermarket parts.

In employing a lot of tensions to the auto exhaust system to make connections, there is a tendency that its parts could foul the body. The occurrence of which could produce repulsive noise and detrimental damage. In fact, it could even lead to eventual separation.

Some vehicle owners think that clamps that secure the catalytic converter and other sections are costly like the U-bolts used somewhere else in the system. The truth, according to auto parts dealers, is the exact opposite. The thick pipe ends on the converter need clamps that can withstand anywhere from 30 ft-lb of torque at the low end to more than 60 ft-lb at the high end. Moreover, when the original equipment clamp is a high strength type with a welded saddle and hardened nuts, experts advise the use an aftermarket equivalent for replacement.

The exhaust manifold joints that link to the pipes of the system or the fast light-off catalysts are other problem areas. A sealing ring found in the joint with the pipe could be noisy when there are leaks. Said joint gets a lot of pressure from engine’s vibration. Despite the presence of spring-loaded bolting setup to maintain tension, it does not serve a lifetime setup. Coil springs could break and joint loosen hence; the system is always at risk.

To maximize the efficiency of the exhaust parts, vehicle owners should choose meticulously engineered exhaust system. In addition, the quality exhaust should be coupled with maintenance and regular inspection to preclude unnecessary expenditure in the future.

Diesel Exhaust Systems

Friday, February 26th, 2010

If you’re looking to improve the overall performance of your vehicle, the first step in this process is upgrading from a stock exhaust system to an aftermarket exhaust system. I recently just purchased a diesel exhaust system for my truck and in this guide I’ll discuss some important information you should know before making your purchase.

There are several different styles to choose from when searching around. However, it’s all just a matter of preference. All these styles will improve your vehicle in several ways, since the car-makers leave us room to improve our vehicles. They just use cheaper options!

The most common reason car lover’s upgrade their cat-back system is for power. You’ll instantly increase the horsepower and torque of your vehicle. The reason for the increase in power is due to the fact that the air flow from the engine improves since it now breathes more efficiently.

You’ll also find that your car starts to stand out a bit more. An aftermarket diesel exhaust has a beautiful tone to it. You’re car will know sound louder and have a smoother noise as you drive.

Another great improvement you’ll notice is you sure won’t be spending as much money on gas. The emissions system starts working in your favor, so you won’t burn up and waste as much gas.

Now that we’ve discussed the three most significant improvements to your vehicle, let’s discuss a few of the different styles available. There are single exhaust systems and dual exhaust systems. Dual systems have less restriction than single systems. The gases leaving your vehicle have more room to escape, which will usually create a better sound and a bit more power.

My recent diesel system is on my truck. Since I often use a trailer, I opted to go with an opposite side dual exhaust system. This is a bit more unique and I recommend it for vehicles that may tow something, like a boat. This style has the pipes coming from under the back bumper and out the sides over the tires. With this style, the gases won’t shoot all over the trailer!

Every time I drive a vehicle with a stock exhaust it really makes me appreciate my diesel exhaust that much more! If you’re looking for a change to you’re car you’ll be happy once you’ve added a new exhaust! Good luck and drive safe!
