Maxim Silencers Catalyst Elements
Maxim Silencers catalysts are developed and manufactured under the strict direction and supervision of the most competent catalyst experts in the world. Our catalyst experts pioneered the very first exhaust catalysts in the 1970’s. Our experts have over 35 years of developing and improving catalysts, 28 catalyst related patents and over 30 years of manufacturing quality catalyst products. Maxim Silencers are proudly made in the USA.
In-House Every Step of the Way
In-House Design and Development
- CAD design and evaluation
- Complete laboratory with prototype development and testing
- Customizable catalyst formulations tailored to individual applications
In-House Manufacturer of Components
- Substrates – Honeycombs
- Sheet metal housings and frames
- 100% Quality inspection ensures product conformance
Platinum Only
Precious metals do the catalyzing, platinum is the most powerful and efficient. We DO NOT substitute platinum with inferior cheaper catalysts such as palladium. (palladium should only be used in special unique super high temperature situations, not as a substitute for standard products and applications)

- 0.003” positional reproducibility
- MIG welds at up to 45 inches per minute
Anti-Telescoping Bars: NO BRAZING! We do not use brazing to counteract the effects of backfires. R&D and field reports indicate brazing leads to brittle areas around the weld-bead. We use anti-telescoping bars, these bars grow and shrink with the rest of catalyst during thermal cycles, proving to be more reliable and less susceptible to failure.
Heat Treat and Coating: Substrates are heat treated in a large kiln and prepared for catalyst coating
- Catalyst coating applied between kiln firing stages
- Finished honeycomb catalysts can then be welded into larger arrays
Crystal Size: Common mis-belief: “More surface loading is better.” The Truth: Crystal size is KEY to catalyst capabilities and efficiency. The patented crystallization process produces smaller crystals. Smaller crystals create more surface area for catalysis to occur. This results in greater and more efficient catalytic effect, on a smaller load area.
