Should I replace my exhaust back-box?

Replacing your original back-box with a sportier sounding performance exhaust back-box from Akrapovic, Cobra Sports or Scorpion is a great antidote to this. The original back-box will have been a compromise tilted towards quietness but an aftermarket performance back-box can be set-up for any sound the manufacturer desires.

Is it possible to make the exhaust centre and back box one piece?

It’s not uncommon to find the exhaust centre section and back box made as one piece, but because exhausts tend not to wear out evenly along their length, you can buy separate sections and cut and join in new sections.

How do you install an exhaust system on a car?

Continue installing the pieces of your exhaust system as you work back toward the rear of your vehicle. Place a gasket over the downpipe with one of the bolts. A gasket is a thin piece that fits between pipes to prevent any leaks from escaping the connection. Hold the port at the end of the downpipe steady and lay the gasket on top of it.

What are the parts of a car exhaust system?

A car exhaust system generally consists of five or six distinct sections: a manifold, downpipe, catalytic converter, diesel or petrol particulate filter, centre section and back box. Because most of a car’s exhaust is slung beneath the body, it’s exposed to all that the British weather – and roads – can throw at it.

How to replace exhaust system without disturbing engine?

Start by disconnecting the bolts and wires of the old exhaust system from underneath your vehicle so you can remove it.

Why is my exhaust water brown?

This might occur if the outside temperatures are pretty low or humidity is very high. The water might actually be brownish due to the dirt inside the exhaust system. Should you encounter larger amounts of oil or unburnt fuel, please stop the process and ask AAA/ADAC or your local workshop for help, as this might indicate more serious damage.

What is the resonator in an exhaust system?

The resonator is a slightly wider section of your exhaust pipe that helps reduce the amount of noise when you run your engine at certain RPMs. Not every exhaust system will have a resonator. The muffler is the large metal box near the rear of your vehicle that helps reduce the amount of noise your exhaust makes.

What is the exhaust system made of?

Choose a system that’s within your budget and is made from stainless steel so it’s less likely to rust or corrode after heavy use. Order the exhaust system you want so you can install it on your vehicle.

Why does my exhaust get hot?

Exhaust fumes can get extremely hot while you’re driving, which can cause the pipes to heat up and cause burns. If you’ve driven your vehicle before you want to install the new system, put it in park, turn off the ignition, and allow the engine and pipes to cool down.

How to find exhaust system?

Familiarize yourself with the parts of the exhaust system. Look up diagrams for the make and model of your vehicle so you can locate the exhaust system. The exhaust system starts with the manifold, which is the section of 4–8 pipes that connect to your engine guide the fumes underneath your vehicle through a metal downpipe. Look for a long pipe that has metal boxes near the front and back and runs from the engine to the vehicle’s rear.

What is the tailpipe on a muffler?

The tailpipe is the small section of tubing that connects to the back of the muffler and allows the fumes to escape into the air.

What are mufflers used for?

In general, mufflers are categorized into three types: 1 Chambered (retro-chambered) mufflers: Feature a series of inner walls/chambers that vary in length. These walls bounds off sound waves for exhaust noise cancelation. Chambered mufflers feature no packing material. They are used to produce specific exhaust note ideal for muscle cars interested in throaty performance sound. 2 Turbo mufflers: They feature perforated S-shaped tubes that guide the exhaust gases out of the muffler. The S-shaped tubing allows the gases to be soundproofed more. Some turbo mufflers include a sound deadening packing that further reduces exhaust noise. Turbo mufflers are ideal for street application. 3 Straight through or glass pack mufflers: Such mufflers are engineered to allow maximum gas flow through. This results to more horsepower output. Glass pack mufflers usually feature a perforated straight through tube buffered by fiberglass or any other soundproofing material. They are great for rally and race cars as they allow little restriction to gas flow. Custom car builders also tend to love them. Compared to the three, glass pack mufflers are the most compact in design.

What is a straight through muffler?

Straight through or glass pack mufflers: Such mufflers are engineered to allow maximum gas flow through. This results to more horsepower output. Glass pack mufflers usually feature a perforated straight through tube buffered by fiberglass or any other soundproofing material. They are great for rally and race cars as they allow little restriction to gas flow. Custom car builders also tend to love them.

How does a back box work?

When you internal engine combusts, it exhausts both gas and sound waves. These sound waves magnify as they travel through your exhaust pipes. If not regulated, they may cause an annoying sound. Back boxes are thus strategically placed at the end of the exhaust system (usually seen at the back of your car) to dampen or knockout these noises before they reach the atmosphere. But how exactly does it work? Well, your back box is designed with buffered chambers or perforated tubes that tune your engine’s sound output. As noise enters the silencer/muffler, the sound waves bounce around and end up canceling each other. The result is gas excretion with little to no sound. As an acoustic device, engineers know how to tune the mufflers to provide a specific sonic effect when exhausting. So depending on whether you want to significantly reduce sound output or get a particular amplified growl choice, there is a muffler out there for you. Your engine also needs to get rid of exhaust gases in order to absorb in the fresh air and thus produce more power. The more active the exhaust flow, the better your engine performance. This makes mufflers dynamics quite crucial in regards to a car’s performance. The sound is dampening action occurring in back-boxes limit exhaust flow by creating back pressure. This is why performance car enthusiasts detest mufflers. But according to most state laws, driving without a muffler is prohibited. With such strict regulations, aftermarket manufacturers are forced to design mufflers that maximize on performance without compromising noise mute. Such mufflers are usually seen on race cars and drifters. Puzzlingly enough some manufacturers prefer engineering super quiet mufflers. The pin-drop silence forces them to strategically design engine noises for more audio feedback on the engine’s condition.

What is a turbo muffler?

Turbo mufflers: They feature perforated S-shaped tubes that guide the exhaust gases out of the muffler. The S-shaped tubing allows the gases to be soundproofed more. Some turbo mufflers include a sound deadening packing that further reduces exhaust noise. Turbo mufflers are ideal for street application.

What is a back box?

A back box goes by many names. In America, it’s commonly referred to as a muffler while the UK scene identifies it as a silencer. Either case, a back-box plays an essential role in your car’s exhaust system. Here’s why.

Why is exhaust failure important?

An exhaust that has failed can lead to noxious fumes being drawn into the vehicle cabin and prolonged exposure to exhaust fumes can make a vehicle occupant feel drowsy, which could lead to an even greater danger, so it’s important to maintain a healthy exhaust system.

Why do exhaust parts fuse together?

Sometimes the different parts of an exhaust fuse together because of a build-up of heat and they are starting to corrode. This can make separation of the individual parts extremely difficult.
