STAINLESS STEEL PERFORATED TUBING FOR EXHAUST
THE NEWEST ADDITION TO OUR CAPABILITIES: PERFORATION
Metalfab Group is now boasting our newest capability: Tube perforation from our hot-off-the-assembly-line Sanderson TPM6. The Sanderson machine allows us the flexibility to perforate our standard stainless steel tubing sizes as part of our current exhaust manufacturing division. The ability to manipulate sound is key for any exhaust applications and this machine allows us to manipulate the amount and length of perforation, giving our customers plenty of options. The result is a custom sound profile for each application that solves the customer’s specific needs.
PRODUCTS

TURBO MUFFLER INTERNALS
Most “Can” mufflers use a variety of chambers to cancel sound waves. This example uses two perforated tubes and is usually wrapped in either a fiberglass or steel wool.

STRAIGHT THROUGH INLINE MUFFLERS
These types of resonators or mufflers use a “core” of perforated tubing to create a chamber. They are usually slid into the larger diameter tubing and welded in place.
We offer standard sizes and lengths of perforated tubing for these products, but give us a call if you have any special sizes or perforation requirements and we will get you a quote.
KEY COMPONENTS WHEN DESIGNING EXHAUST SYSTEMS:
LONGEVITY
The use of 304 Stainless Steel allows for a long lasting quality product. Our stainless is high quality and sourced from American factories.
SOUND DESIGN
When it comes to perforated tubing for exhausts, the goal is to reduce sound levels while maintaining engine performance. The type, size, and amount of chambers or perforations used in the exhaust system will define the needs from the sound design of the part. Our engineers will work with you and identify a solution that satisfies the sound and performance you need.
FITMENT
In a perfect world, we’d have all the room we need to build the perfect system for your application, but in the real world there are constraints requiring parts to fit allowances and installation considerations. We can design a system that uses sweeping mandrel bends and break points to allow for a system to be assembled from sections.

INDUSTRIES WE SERVE:
AUTOMOTIVE
We’ve been building American muscle car exhaust systems for twenty five years. Whether it is performance exhaust systems or OEM replacement systems, we can design and build it all.
POWER GENERATION
​We build muffler systems used in small and large generators for some of the biggest names in the industry. From on-truck welding generators to industrial generators, we can build the solution you need on your newest products.
HEAVY EQUIPMENT
​In the heavy equipment industry, we build quality replacement products for brands like John Deere, Caterpillar, and Kubota to name a few.
