F.A.Q's
Q. What about the valve, why doesn't this product also delete that?
A. Deleting the valve will change the volume and tone of your system but it is not necessary to remove it. Here is a
link to a video explaining how to simply get it to stay open and how it sounds stuck open compared to functioning properly. Here is
another video if you have one of the newer round style flapper valves.
Q. Will upgrading to a B2 Fabrication exhaust system improve my Silverado's performance?
A. Yes, well very 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.
Q. What do they sound like?
A. 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.
Q. Can I install the B2 Fabrication muffler delete myself?
A. 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.
Q. What models are compatible with B2 Fabrication muffler delete?
A. The B2 Fabrication exhaust systems are designed to fit all 2014-2025 Chevrolet Silverado 1500 and GMC Sierra models with a 5.3L engine. Fits all wheelbases, cab configurations and bed lengths. We also have one for the 6.2L on another listing.
