Why do you need a X-Pipe

http://www.magnaflow.com/02product/02xpipekits.asp


Although X-pipes are essential for race cars, adding this modification to a stock car can be a good idea for many reasons – increased power, fuel economy and less noise inside the vehicle. This type of aftermarket performance part is something you can either purchase or have custom-made for you by a good muffler shop (like us of course). Installation is usually simple enough for the at-home pro, but for custom installations a professional installation might be required.

The Evolution of the X-Pipe

To understand the importance of the X-pipe in relation to improved performance and power, you have to know about its roots. The X-pipe is really the offspring of the H-pipe design, which was first conceived in the 1960's by the major American car manufacturing companies at the time. Duel exhaust pipes for V-8-powered vehicles are very noisy, as there is no sound wave cancellation between the 2 separate four-cylinder engines and unconnected exhaust systems. Engineers were looking for a way to cut down on interior noise levels and improve the engine's power. They realized that running a balance tube between the two branches of exhaust pipe would work to broaden the torque curve (thus improving engine performance) and dissipate sound resonance in the exhaust system.

In the 1990's improved technological advancements made it possible to construct an exhaust pipe that, instead of connecting by means of a balance pipe at a severe 90-degree angle, could unify the two branches of pipe to create a flow of exhaust in one direction.

Now X-pipes are being manufactured for popular performance cars, usually off-road versions minus catalytic converters, but you can also find them in legal models fully equipped with proper emissions equipment. Performing an X-pipe mod is an option that you should consider.

Why X over H?

It has been proven time and again that the X-pipe design is more efficient than the H-pipe. Various tests have shown that for multiple cylinder engines the X-pipe outperforms H-pipe exhaust systems, especially as rpm increases, providing both better torque and power. Unified exhaust pipes work most efficiently with multiple cylinders because of the scavenging effect. With exhaust X-pipes the almost seamless connection between the two exhaust pipes allows sequential firing cylinders to salvage any spent exhaust gases from the combustion chamber more efficiently and creates more room in the cylinder for a fresh intake of undiluted fuel and air. When you have two exhaust pipes, as the velocity in one header tube increases, the pressure in the adjacent tube is lowered causing the exhaust to be sucked out of that cylinder. X-pipes are simply better at doing the job, especially at higher speeds.

Installing Exhaust X-Pipes

This is a simple mod that almost anyone can perform successfully. Most companies produce exhaust X-pipes that are simple bolt-ons that can be installed in less than an hour using the usual hand tools.

If you own a vehicle that doesn't have an X-pipe available, it is possible to have a custom X-pipe assembled for you. Alvin Muffler shop can construct it by taking an X-pipe union and bending up some exhaust tubing until it fits.

All in all, with exhaust X-pipes torque and power will increase resulting in fast acceleration, improved fuel economy and a nice quiet ride. The difference is noticeable with the installation of X-pipes on a V-8 engine vehicle - interior noise is reduced considerably because you don't hear the firing impulses of 2 four-cylinder engines, but instead hear the noise of all 8 cylinders blasting out of both pipes at once.

Shade Tree Automotive Diagnostics And Care - Part III - Smell No Evil



It may sound strange that smelling your vehicle can be a useful maintenance activity, but believe me it is. And I'm not just talking about needing to buy one of those cute little green trees that permeate every inch of your vehicle's interior with the smell of pine – or something like that. Actually, you really already do this in at least one instance – the smell of gasoline. And we'll cover that herein.

Let's begin with the smell of smoke. If your vehicle is smoking anywhere at any time it's time to get some service – immediately. It doesn't matter if you smell the smoke, or see it – you need to deal with the problem ASAP. Smoke coming from anywhere is never 'okay' in a vehicle, though you may just have some spilled fluids on a hot engine surface, or some oil that splashed into your wheel assembly. No matter – get it checked and make sure.

The smell of gas is most often associated with a flooded engine: too much gas for the spark to ignite. The gas sits in the engine, and the odor becomes more noticeable for a short time, and then starts to rapidly dissipate. This tends to happen only when you are starting the engine. The smell of gas at any other time, or the constant smell of gas is indicative of another type of problem, and one that is potentially serious, or dangerous: a leak in the fuel system. You should have this checked out by a qualified mechanic as soon as possible.

The smell of rotten eggs, usually associated with sulfur or burning sulfur, is likely a problem with your catalytic converter. Servicing a catalytic converter is highly technical, and will require the attention of a trained Muffler Shop like us. You should make an appointment for your vehicle as soon as possible. A maladjusted or failing catalytic converter can be costing you precious mileage!

The smell of burning bread, sometimes referred to as 'burnt toast,' is most often associated with an electrical short circuit or possibly the burning/melting of the insulation around the affected wires, fuses, or connections. If there are any secondary signs, then you should not run the engine until a qualified technician resolves the issue. Left unchecked, electrical shorts can affect many of the systems in your vehicle.

A sweet odor, especially when mixed with the smell of hot rubber, usually means there's a coolant leak, or a problem with the cooling system. If you are driving, stop and visually check the engine and the radiator. Driving a vehicle with an overheated engine can do untold damage to all sorts of things, and turn a simple repair with a modest cost into a nightmarish expense that prevents you from using your vehicle for days, or even weeks.

The smell of burning oil is a pungent, acrid stench that can be very slight, or quite pronounced. In either case, you need to check your engine to make sure you don't have an oil leak, and also to ensured that you have the recommended amount of oil in your engine. Usually, the smell of burning oil is something minor, such as a small spill on the engine, a slight overflow that got blown onto a hot engine part, or low engine oil.

Okay, you've completed the final step in becoming a full-fledged automotive diagnostician – or something like that, anyway. You've definitely gotten your vehicle in much better condition, and you should have learned a thing or two to keep it running great for a long time to come. If you haven't already, check out Part I – See No Evil, and Part II – Hear No Evil.
