Chevrolet Silverado is a powerful, full-size pickup truck to handle heavy loads. Its exhaust system is essential to have the burned fuel and air mixture removed. So, even if the factory one is efficient in the sound muffling, creating sufficient backpressure, there comes a time to change it. Why does it? It is necessary to improve the driving, making the gases to escape fast and easily. The best exhaust system for Silverado 1500 increases power, decreasing pressure while getting rid of fumes and increasing the BHP (brake horsepower).
So, don’t forget to take into account the sub model and the engine type (for example, 4.3L or 6.2L) and let’s think about the preferable type and material. Which parts – cat-back or axle-back are better? Which material to prefer – aluminized or stainless steel? Let’s go into details.

7. Truck Exhaust Kits: High-performance Exhaust System
Do you want to save on your cherished Silverado Vehicle? If you are upgrading it, I am sure you don’t. Just make a great investment. Customizable system by Truck Exhaust Kits is durable and top-quality. Aluminized steel is perfect material. It’s lightweight, heat-resistant, and rust-proof.
Have you decided to convert your single exhaust system into a dual set? It’s a wise decision. It lets you improve performance of your heavy-duty truck. You get more horsepower due to faster air moving. It means faster cylinders and engine operation. Being a responsible driver, you’ll appreciate it for sure.
Parts and Installation Issues
You can be a budget-minded car enthusiast. Price matters, but it’s not decisive. You get a complete system in a parcel. Basic parts and hardware are available. They include:
- Ф top-quality (1 chamber) Flowsound muffler.
- 18-inch long mandrel-bent tubes.
- 9 saddle clamps.
- 4 rubber hangers.
- 2 slash-cut tailpipes.
The manufacturer recommends professional installation. The kit is not the easiest DIY accessory. What is the challenge? The muffler comes with a 3” inlet. You may need an adapter to connect it to your truck’s catalytic converter. Additional pipes might be necessary.
If you’ve got a regular cab model, the pipes would be too long. With a couple, two, three adjustments, you can install it yourself. So, you get deep, loud sound. Moderately aggressive muffler enables pleasant throaty tone. I also like the way tailpipes look! They are so shiny and elegant.
Don’t forget to check the fit. There are several Shop Line exhaust system sizes. This kit suits all wheelbases, but only 8 or 6-cylinder gasoline engines.
What is the Best Material for Exhaust?
Aftermarket, performant exhaust systems are commonly made of various rust-resistant, long-lasting alloys. The parts built from aluminized steel, are covered by aluminum-silicon alloy by hop dip method, while the piping inside is metal, heavy-duty and strong. These constructions are extremely lightweight and corrosion-resistant. But, they are still not so long-lasting as the stainless steel systems, being usually covered by 3-year manufacturers’ warranties.
The 409-grade stainless alloy that includes chromium and titanium is among the most recommended ones, as it stands out by corrosion-resistance, strength, durability, and cost-efficiency. Additionally, 304 – grade steel with nickel and chromium content is among the best materials for top-quality, reliable exhaust systems’ production, coming with lifelong warranties.
What is a Cat Back Exhaust System?
It is designed for replacing some system’s components. The system starts with the back of the available catalytic converter, consisting of several parts such as a muffler, tailpipes 1 or 2 tips and connection pipes. This type of exhaust system is the most popular. The other one is an axle-back system that includes only the tailpipes and sometimes a muffler, missing some piping parts.
What is a Full Exhaust System?
It commonly includes an exhaust manifold, a catalytic converter and a cat-back system itself. The catalytic converter can be removed completely or replaced with a high flow unit; the manifold is often replaced with headers, to allow less restrictive airflow and increase the Silverado truck’s horsepower.
What Type of Muffler Should I Get?
Mufflers can be positioned in different ways such as in direct lines with the pipes, in a side-to-side position (with 2 tailpipes). However, the basic muffler types are:
- chamber one, coming with a filter, producing the specific sound tone, as it cancels out the sound waves;
- straight-through muffler that consists of:
- a straight, perforated pipe;
- fiberglass isolation;
- steel wool.
Buyers’ Guide: How Does the Best Exhaust System for Silverado 1500 Works?
Your pickup truck’s engine produces power, creating waste gases that are to be removed fast and efficiently. Therefore, the exhaust system stipulates the vehicle’s performance and power.
Initially, the manifold carries the exhaust gases (emissions) to the catalytic converter, that reduces the toxins and harmful substances amount in the gas.
Afterward, the exhaust pipe carries the gas to the muffler, designed for reducing the noise. Therefore, the customers, who think about how to choose a muffler, want to get a loud, aggressive, or pleasant sound to feel great or just to avoid vibration, drone, and headache.
Tailpipes and tips are the last system’s section. They are offered in great versatility, being of various diameters, constructions, made of different steel alloy, and the truck performance depends on your choice.
How to Improve the Silverado Vehicle’s Performance?
Upon the installation of an aftermarket, top-quality exhaust system, the emissions flow is optimized by:
- eliminating restrictions;
- increasing the pipes’ diameters;
To have the emissions evacuated fast and restriction-free, minimize the backpressure, the pipes’ diameter shouldn’t be reduced. Therefore, the advanced, mandrel bending method is applied. A flexible, inside steel rod is used to avoid collapsing or wrinkling from the inside or crushing. Therefore, the inner pipe’s diameter doesn’t change, and the recommended Gibson system is a good example.
Quite naturally, the pipes diameters are to be as large, as possible. They provide high, more efficient flow, maximizing the engine’s power and torque. Scavenging means vacuuming effect that pulls exhaust gases out and draws oxygen quickly into the cylinders. It happens when the exhaust pipe installed is fine-tuned and restriction-free. Additionally, a rumbling, aggressive sound is to be produced, and it depends on the muffler.
Single vs. Dual Exit Systems
The exhaust systems, coming with the only one tailpipe and one tip, are great for upgrading as they ensure significant performance, horsepower and torque gains over the factory parts. It is achieved due to beneficial mandrel bends and large tube diameters. These systems are commonly more lightweight than dual-exit ones, and easy to install, requiring no adjustments or welding.
On the contrary, the exhausts that come with 2 tailpipes and 2 tips, are preferable due to perfect, hot rod styling, but are similar to the single-exit ones in terms of performance.
The Other Factors to Consider
Knowing the complete answer to the question “What is cat back exhaust systems for trucks like Silverado 1500?”, check also your pickup submodel and engine type. Selecting the aftermarket parts, pick out only the systems that are:
- top-quality and reliable;
- mandrel bent.
A large pipe diameter is preferable, but the difference from the factory one should not be too significant, to avoid the engine power loss.
Additionally, wondering what muffler fits my truck, I am to calculate its size according to the flow rate, the Silverado engine’s HP and the pipe diameter. However, picking out one of the recommended items, you can disregard all of the estimations, as the manufacturers have already responded to all of the factors in the best way.
All of the Silverado 1500 exhaust systems I recommend herewith are durable and reliable, easy to install, powerful and stylish. All of them ensure from 5 to 10% of torque, power and mileage increase, offering the significant fuel economy. However, for long-lasting use and lifetime warranty, select the kits that are made of the most rust resistant, 304-grade steel, like the Borla and Dynomax systems. Additionally, the Flowmaster products offer premium, stylish design due to dual-exit construction; the Gibson’s exhaust’s look is unique because of black, ceramic-coated, large-diameter tip.
So, don’t forget to check your Silverado 1500 submodel and engine type fit, spend only about an hour or two on the installation. And start taking the great aftermarket parts’ and the best exhaust system’s benefits.
