Background
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.
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.
Solutions
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.
Replacement
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.

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.
