Sone304 -

A true Sone304 product will include a graph showing sone rating at idle, 2,000 RPM, 3,000 RPM, 4,000 RPM, and WOT. If a seller cannot provide this, they are using the term as pure marketing fluff.

Sone304 is almost certainly a typographical variant of SUS304 (304 stainless steel). It is a versatile, affordable, and corrosion-resistant alloy perfect for hundreds of applications. However, always verify with documentation – and when in doubt, search for the standard AISI 304 or EN 1.4301.

Report: Sone304

Introduction

The term "Sone304" appears to be a designation that could refer to a specific material, product, or project. Without a clear context, it's challenging to provide a precise report. However, assuming Sone304 refers to a material or alloy, which seems a plausible interpretation given the alphanumeric nomenclature often used in materials science (e.g., SS 304 for stainless steel 304), this report will proceed with an educated guess that Sone304 might relate to "SS 304" or a similar industrial material.

Material Overview: SS 304

For the purpose of this report, let's consider that Sone304 could be a misnomer or variation in naming for SS 304, a widely used stainless steel alloy.

Never use mild steel filler on "Sone304"; it will cause galvanic corrosion at the weld.

TIG (Tungsten Inert Gas) welding produces smoother internal seams, reducing turbulence. MIG welds have "splatter" that creates micro-eddies, increasing perceived sones by 0.5–1.0.

False. A well-engineered Sone304 exhaust reduces backpressure while managing volume. Many factory exhausts have high backpressure AND high sones (due to poor resonator design). Quality aftermarket systems drop both.

You’ve bought your Sone304 exhaust. Now, how do you install it to ensure those sound targets are met?
