Stainless Bros 4in Perforated Punch Tube 20in OAL - SS304

This is a 4-inch diameter, 20-inch long perforated punch tube from Stainless Bros, made from SS304 stainless steel. It’s designed for custom exhaust fabrication projects where you need to create a muffler core or a resonator. The perforations allow exhaust gases to flow through while helping to manage sound.

The SS304 stainless steel construction means this tube is well-built to resist corrosion, which is important for exhaust components that are exposed to heat and moisture. Its 4-inch diameter and 20-inch length offer a good amount of material for building a custom muffler or resonator that can be tailored to your specific needs. The punch pattern on the perforations is a common choice for mufflers, as it provides a balance between sound dampening and exhaust flow.
