01. Flowmaster 17395 Cat-back System – Dual Same Side Exit

The mandrel bends are gentler and they do not leave the metal kinked or folded so they do not slow down the exhaust being expelled.

When you have a greater amount of flow like you have with this exhaust system you get an increased amount of torque and you also increase the horsepower your engine has.

Another benefit of greater exhaust flow with less restriction is the increased fuel mileage that you get. This exhaust system has all of the hangers and hardware that you will need to install it.

How to Choose the Right Exhaust System for Your Silverado 1500

When you are considering a new exhaust system for your Chevy Silverado you have to consider what kind of driving you do the most in order to choose a system that is best for your needs.

There are a few other things for you to consider that will help you to get an exhaust system that performs best for you.

City or Off-Road Driving

If you drive your vehicle primarily in hunting clubs, or down dirt roads, or on race tracks, then you do not have to worry about the decibels your exhaust system creates. You have to worry about how much ground clearance you have so your exhaust pipes are not damaged by rocks or road debris.

If you drive in towns, or around neighborhoods with homes, then you have to consider how loud your exhaust system will be. Some towns have noise ordinances that will stop you from driving a vehicle that sounds very aggressive or loud. Always check your local regulations prior to buying a new exhaust system.

Where do the Pipes Exit the Vehicle

One thing you may not have considered about your exhaust system is where the pipes will exit the vehicle. Do the pipes come straight out the back, or will they exist in front of a tire on the side of the vehicle.

The position of the pipes as they come out from under the vehicle can be a determining factor in whether the exhaust system will be beneficial to you on your vehicle. Take exact measurements and make certain that the system will fit your truck properly prior to buying.

Pipe Size

The diameter of the exhaust pipes can make a large difference in the sound of the system. Larger diameter pipes allow a free flow of exhaust and that allows your vehicle to have a more aggressive sound.

Narrow or small diameter pipes restrict the emissions and dampen the noise created by the exhaust.

Pipe Materials

When you are selecting an exhaust system remember that the pipes will be under your vehicle and they will be splashed with water, hit by bits of road debris, and subjected to heat and cold.

Buy pipes that are made from aluminized steel or stainless steel to ensure the proper strength and agility.

Final Thought

When you go to buy an exhaust system for your vehicle you need to be sure that you are getting a system that is legal for highway usage. Many exhaust systems are designed for off-road use only, and they create noise levels that are not permitted in some places.

Always check your vehicle warranty information to make sure that changing your exhaust system will not void your manufacturer warranty. If you cannot find this information talk to the dealership and they should be able to answer this question for you.

Always measure the bed of your truck, and if possible your existing exhaust to make certain you are getting a system that will fit properly.
