Harley-Davidson and Indian Motorcycle riders know that maintaining your bike isn’t just about keeping it looking good – it’s about ensuring peak performance. One essential aspect of upkeep is cleaning and maintaining your exhaust system. A well-maintained exhaust not only prolongs the life of your bike but keeps that signature roar as powerful as ever. This guide will walk you through the best ways to clean and maintain your motorcycle exhaust, ensuring your ride stays top-notch.

Brushed Stainless Steel finish

• General cleaning – clean cotton cloth and soapy water
• Heavy duty cleaning – mineral spirits, denatured alcohol, simple green or WD40 and red & gray scotch brite pads

Ceramic Coated finish

• General cleaning – clean microfiber cloth and soapy water
• Heavy duty cleaning – mineral spirits, denatured alcohol, or simple green and clean microfiber cloth

Mirror Polished finish

• General cleaning – clean microfiber cloth and soapy water
• Heavy duty cleaning – mineral spirits, denatured alcohol, simple green or chrome polish and clean microfiber cloth

1. Let your bike cool down before you start. Don’t clean a hot exhaust.
2. Use a hose to rinse off loose dirt and debris.
3. Use some soapy water (we prefer dish soap) and a cotton rag (for brushed stainless) or microfiber cloth (ceramic coated or mirror polished) to wash away any grime, dirt or oil.
4. Rinse thoroughly with clean water.
5. Use a clean and dry cotton rag or microfiber cloth to dry the exhaust completely.

3. For stainless exhausts, you can use a razor blade to carefully scrape off any excess or built up material.
4. Spray or pour your cleaning solution of choice onto your scotch brite pad (for brushed stainless finish only!) or microfiber cloth. Apply to areas that need attention or the entire exhaust exterior.
5. Scrub gently to remove any built up grime.
6. Rinse thoroughly with clean water.
7. Use a clean and dry cotton rag or microfiber cloth to dry the exhaust completely.
   

• Don’t clean a hot exhaust!
• Avoid using Purple Power or any acid-based cleaners or harsh solvents
• Avoid using a grinder, heavy sand paper or files – these can leave heavy gouges in your pipe.

Our brushed stainless steel finish exhausts are very easy to restore to that factory finish! If your stainless exhaust is showing any light scratches, use a red scotch brite pad and rub in a circular motion around the pipe, being sure to match the grain mattern. Then use a little WD40 and a gray scotch brite pad to wipe clean.

We also get asked a lot about Blueing, which is discoloration in your head pipes. This typically affects brushed stainless finished exhausts and varies bike to bike, but usually heavy blueing is a sign that your fuel mixture is too rich. Blueing and gold coloration are normal.

Regular inspections are key to maintaining your exhaust system. Aim to inspect your exhaust at least once a month, possibly more frequently if you put on a lot of miles. And it’s always a good idea to inspect prior to departing on a big trip.

• Mounting points – ensure all mounting bracket bolts, muffler bolts, end cap bolts and flange bolts are secure and free of damage.
• Leaks – check for any signs of exhaust leaks, such as soot marks or unusual noises.
• Heat shields – if you run Sawicki Speed heat shields, check the connection points on these as well.

Make Adjustments

If you notice minor issues, such as loose bolts or connections, go ahead and tighten them. Refer to your exhaust’s installation instructions if you run an aftermarket exhaust, or your motorcycle owner’s manual if you run a stock exhaust.

When to Go to a Professional

If you encounter any leaks or structural problems with your exhaust, mounting hardware or connection points, you can contact us at support@sawickispeed.com or contact your local motorcycle dealership or shop. We also recommend staying on top of your motorcycle manufacturer’s recommended service intervals.

Cleaning and maintaining your motorcycle exhaust is an essential part of keeping your Harley-Davidson or Indian Motorcycle running smoothly and looking great. By keeping your exhaust clean and performing regular inspections and maintenance, you can extend the life of your exhaust system and focus on your riding experience.
