(FAQs) of Best Exhaust for 5.3 Silverdo

What are the different kinds of exhaust for 5.3 Silverdo?

The 5.3 Silverdo, featuring different models that support different exhaust build types, has a number of exhausts that can fit into it.

Single Exit pipe

The simple exit pipe is quite common among a few models of the Chevy Silverdo.

Being that they aren’t as efficient as other types of exhausts featured in the 5.3 Silverado,  they’re quite affordable and very easy to install.

The pipe exit is located at the passenger’s side of the vehicle.

Dual-rear exit

5.3 Silverdo is also compatible with the dual rear exit exhausts. They make models that support this exhaust type look sportier than models that feature the single exhaust.

They also offer a user deeper notes, giving the engine a more powerful sound. The adapted system of this exhaust type consists of two pipes, positioned at opposite sides of the vehicle.

The unique thing about the dual rear exit is that they don’t bed around the wheels, which is a clear distinction among other types.

Opposite dual exhaust

Opposite dual exhausts, unlike dual rear exit exhausts, have a slightly different working mode.

For Chevy Silverado vehicles that have this kind of exhaust installed on them, you will find them wrapped around the vehicle’s wheel while using the bend as an additional filtering mechanism.

Dual side exhaust

From the name, it simply means that this system supports two exhausts that lie side by side next to each other, rather than on opposite ends.

This double exhaust system expels gases more efficiently than single exhausts.

They also offer some performance enhancements. Dual exhaust systems have also been reported by buyers to better performance gains, thereby providing additional power gains.

The 5.3 Silverdo is also known to use the cat back aftermarket exhaust system, which is one of the three most popular types – header back, cat back and axle back.

Cat-Back

A lot of 5.3 Silverado trucks make use of the Cat-back exhaust system. The Cat-Back exhaust is typical of featuring a muffler and a tailpipe.

They also support mid-pipe, H-pipe, X-pipe, depending on the model. 5.3 Silverado adopts this exhaust system for many reasons

  • It offers a simple modification
  • It makes exhaust gas flow freer
  • Power gains are improved
  • Enhanced engine efficiency
  • More aggressive exhaust note

Reasons why water comes out of my car exhaust pipe?

May be due to water condensation in your engine

Pollutants often form when your engine goes through its typical internal combustion process. This is nothing to worry about, as it is a normal process.

The common pollutants you get are water, carbon dioxide, vapor and nitrogen.

As the exhaust gases make their way out of the combustion chamber, water and carbon dioxide keep mixing. There is now clear visible water coming from the tailpipe.

This isn’t anything to worry about, as it often stops in just a matter of minutes.

A heating up engine

The most heat your engine generates is when you start your car. The oil in the engine requires some time to flow and lubricate the engine component, which ultimately causes them to cool.

The reality though is, while the engine is hot, the exhaust system inevitably is hot too.

If the temperature outside is cold, it will cause water vapor to form in the exhaust. This will again, cause water to leak from the exhaust.

Catalytic converter

This converter reduces the amount of toxic gases leaving the exhaust system. During the process where this is formed, little amount of water vapor is produced. This again causes droplets to leave the exhaust pipe.

Faulty pistons or ring

If your engine’s pistons are faulty, they will initiate excessive blow by. This creates blue smoke, sooty exhaust or oil residue in the tailpipe. This  causes residual condensation.

There are a number of ways you can address this when it becomes abnormally recurring.

Nonetheless, you should know this is a perfectly normal scenario except your vehicle has an underlying need for engine repair. Find out what to do here:

Fix leaking pipes

Before you do this, you have to determine the source of the issue.

Your catalytic converter plays an active role in the condensation process, hence if it comes unusual, you may have to take your vehicle to a professional to examine, and if need be, replace it.

Examine the intake gasket

To examine your gasket, you have to remove the intake manifold. If anything seems wrong or abnormal, a good advice is to have the intake gasket replaced.

Examine the cylinder head

Aluminum is the major component of the cylinder head. In situations where your engine undergoes overheating, it is common to find cracks on the aluminum.

This of course then leads to the coolant dripping. To prevent this, you have to make sure that your cylinder seals your head gasket evenly with the engine block.

How do I add horsepower to my 5.3 Silverado?

If you want more power from your 5.3L Silverdo, here a couple of things you should do. They may all not be necessary to your exhaust, but you can work through them to determine how to imporve your horsepower.

Change your stock filter

Replacing your stock filter with an aftermarket air filter allows air to move more unrestrained through the vehicle’s engine.

This enhances the firing power as there is no residue to limit the production of the air. Air filters provide engines with purer air, hence higher hp which in turn works in improving your experience.

Aftermarket computer chips

They boost your engine’s hp by stepping up the engine’s computer using a programmable ROM. Operationally, they often alter the air/fuel ratio as well as your engine’s spark timing.

Change your engine’s spark plug and wires

Performance plugs make your engine more efficient, enhancing the gaping power. This ultimately, causes quicker and more sensitive sparks, bumping up your engine’s horsepower.

Does a better exhaust system increase horsepower?

An aftermarket exhaust helps the filter to be more efficient in expelling air. Certain features in an exhaust that tend to improve horsepower are a high flow muffler and the exhaust pipe diameter.

Also, some of the features of the exhaust system should always match with the current need. For example, if there is need to conserve more energy or be ecofriendly, this would drive the choice.

On this review, there are several options that should be looked out for and then used to match your particular need. This can be used in determining the actual better option for your vehicle.

What is the loudest exhaust for a V8?

Engines when at work, are not quiet. This is where the need of a great muffler comes in. Without a good muffler in an exhaust, the sound note is often pitchy and loud and quite unpleasant.

V8 engines are notable for having high note sound outputs, so exhausts provide a medium of contained pitch which is within a bearable range.

Nonetheless, some exhausts among top products available in the market, seem to have higher notes than others. A lot of users agree that the Dodge Challenger Hellcat is loud, but at a safe range.

Conclusion.

The best exhaust for 3.5 Silverado must embody features ranging from efficiency to improved power and bearable sound output. This is exactly what the Flowmaster Outlaw Exhaust offers a user. It’s simply magical!
