- Have a project but need a custom exhaust system, cat-back system or headers?

- Don't like the sound of the quiet OEM mufflers on your car or truck?

- Have just a single fitting or O2 Sensor b**g that needs to be installed? At Muscle Tones Exhaust & Fabrication LLC. we have the

tools and skills to get the job done for you at a reasonable price and with the custom small business, personalized touch you're looking for. After all, we're "Car Guys", we take your project seriously and treat your vehicles as if they were our own. We're not your standard "muffler shop" that only cares about installing "cookie cutter", poorly bent and poorly flowing OEM systems, we specialize in premium naturally aspirated/turbo & supercharger piping fabrication, custom thick wall stainless exhaust systems and custom headers for your project. We only use high quality thick wall mandrel bent piping and associated materials and will not sacrifice quality. All of our fabrication is done in house and is TIG welded for quality, strength and appearance. We can also help with your other needs: Custom stainless or aluminum fuel tanks, catch cans, overflow tanks, V-band clamps, O2 sensor b**gs or general welding needs. No mater the material, Aluminum, Stainless, Titanium, Castings or Mild Steels, we can cover your needs. Quality and customer service are my goals with your welding projects and we offer a "Lifetime Limited Warranty" on our workmanship, so if you ever have an issue and we find it to be our fault we'll fix it for you free of charge.

We’re so blessed to have such great customers and such great “word of mouth recommendations.

Making great exhaust systems is easy when it’s fun!

Thanks in advance to all my past, present and future customers. Your recommendation is what we thrive on each year.

As I approach 50 this year, it’s pertinent that I say thank you for all your support over the last 15+ years in business.

They say after 10,000 hours you have mastered your craft, we’re always learning to do better in the end!

I’ve had the pleasure of working on and helping to build some amazing exhaust systems, turbo systems etc.

Building on our passions has been one of the greatest pleasures of my life!

We hope you have many smiles per mile!

Sometimes we actually work on our own projects.

This is what you do when you’re getting old and tied of climbing over rollbars….you add a swing out!

Also buttoned up a few interior pieces that were long overdue.
