Recently, we received feedback from a user reporting rust issues with their stainless steel exhaust pipe components (such as the Exhaust Manifold, Muffler, and Tailpipe). In response, SPELAB conducted a thorough investigation and has proposed the following solutions.

User Feedback Report: Stainless Steel Exhaust Pipe Rust Issue

Future Plans

Based on this feedback, SPELAB has implemented a series of measures. First, we will upgrade the stainless steel materials to better withstand corrosion in the environments our users encounter. To swiftly address these issues, SPELAB is conducting market research on rust removers and plans to introduce a comprehensive rust removal kit soon.

Additionally, as a result of this incident, SPELAB has decided that for rusted CCV reroute kits (such as the CCV Reroute 6.7 Powerstroke, 6.7 Powerstroke CCV Reroute), users can purchase a replacement at half price.

Next, we will outline the solutions for addressing rust on stainless steel exhaust pipes.


To address the current rust issue on exhaust pipes, we recommend the following steps:

Cleaning Rust Spots

Manual Cleaning

Use a stainless steel brush, sandpaper, or steel wool to gently remove rust spots. Ensure you use tools suitable for stainless steel to avoid further damaging the surface.

Chemical Cleaning

Employ specialized stainless steel cleaners or rust removers. These products effectively eliminate surface rust and help restore the stainless steel's shine. Follow the product instructions carefully and ensure proper ventilation during use.

Treatment and Polishing

After cleaning, use a polishing compound and tools (like a polishing wheel) to polish the surface. This not only removes remaining rust spots but also restores the bright surface of the stainless steel.

Preventive Measures

Coating Protection

After cleaning and polishing, apply a layer of rust inhibitor or protective coating to the stainless steel surface. These coatings provide additional protection against future rust.

Regular Maintenance

Regularly clean the stainless steel exhaust pipe to prevent the buildup of dirt and salts. Use mild soap and a soft cloth for cleaning.


Environmental Improvements

If the exhaust pipe is in a damp or high-salt environment, minimize the vehicle's exposure to these conditions or consider installing a protective cover for the exhaust pipe.

Inspection and Replacement

Regular Inspection

Regularly inspect the condition of the exhaust pipe, especially a few months after cleaning and polishing. Look for new rust spots and address them promptly.



If the rust is severe and compromises the structural integrity and performance of the exhaust pipe, consider replacing it. Choose high-quality stainless steel materials to ensure better corrosion resistance in the future.

If you want to gain a deeper understanding of why stainless steel exhaust pipes rust, read on to learn about the causes of rust on stainless steel exhaust pipes.

Causes of Rust on Stainless Steel Exhaust Pipes

While stainless steel is known for its resistance to oxidation and corrosion, under certain conditions, it can still rust. Here are some possible reasons for stainless steel exhaust pipes rusting:

Environmental Conditions

In extreme environments, such as high-salt coastal areas or heavily polluted industrial regions, stainless steel may suffer from pitting or crevice corrosion. Chlorides and other chemicals in these environments can compromise the protective layer on stainless steel, leading to localized corrosion.

Quality and Type

Stainless steel comes in various grades with different alloy compositions. For instance, 304 stainless steel has good corrosion resistance in general environments but may not be as durable as 316 stainless steel in high-chloride conditions. The molybdenum in 316 stainless steel offers enhanced corrosion resistance.

Maintenance and Care

Even stainless steel requires proper maintenance and care. Accumulation of dirt, dust, or other contaminants on the surface can degrade its passive layer, leading to localized corrosion.

Mechanical Damage

Scratches or mechanical damage to the stainless steel surface can expose the underlying metal to corrosive environments, making those areas more susceptible to rust.

Importance of User Feedback

SPELAB greatly values feedback from automotive enthusiasts. Your feedback is crucial for the development and improvement of SPELAB products.
