Chevrolet Silverado Exhaust Systems

The B2 Fabrication exhaust systems are designed to fit all 2019-2024 Chevrolet Silverado 1500 and GMC Sierra models with a 5.3L engine, we also have a muffler delete for the 2020-2023 with the 6.2L. Fits all wheelbases, cab configurations and bed lengths.

The Silverado's and Sierra's come from the factory with mandrel bent stainless steel exhaust systems. These systems are extremely high quality, in most cases a higher quality than aftermarket systems. By only replacing the muffler you will achieve the sound and added performance of a complete cat-back system for a fraction of the cost. The average ear will not be able to tell the difference between the B2 retrofit muffler and a competitors full system for triple the cost.

Most customers do not report any drone, but there has been slight drone occasionally reported around 1500 RPM's with the retrofit muffler, none with the muffler delete, although with both there may be a slight increase in cabin noise at highway speeds, more so with the delete.

The retrofit muffler will have an aggressive sound at start up, then quiets down to a nice low rumble tone. Not loud at all, and most report no drone in cab at speeds.

The muffler delete will be louder than the muffler by about 25%, it will have a higher tone, it can crackle a bit but that tends to go away if you eliminate the flapper valve.

The system includes the direct-fit muffler and tubing, detailed instructions, and all necessary mounting hardware for installation. No additional modifications are needed.

Yes, the installation process is straightforward. It involves cutting out the existing muffler, installing the new muffler, and securing it with clamps. Welding is optional but can be done if you have the capability or by a muffler shop.

It is important to install the clamps properly for a proper seal, a little high temp silicone inside of the joint will help the sealing process. We have designed the slots in the tubing to exactly match the width of the clamp. Line the clamp up with the slots and tighten extremely tight, preferably with an air powered impact wrench.

Yes, slightly. Upgrading to a B2 Fabrication exhaust system can improve your Silverado's performance due to better exhaust flow and engine efficiency, enhancing throttle response, and potentially increasing fuel efficiency by 1-2 mpg.
