COVID-19 Update: Our website offers seamless ordering anytime, and with the exception of business critical personnel, the majority of our customer service, call center sales staff marketing and related support are officially connected and working from home as of Monday, March 30, 2020. Like most fulfillment centers, you’ll likely experience some delays in shipping, as our Warehouse team is running at reduced capacity. We are continuing to take extra precautions with additional cleaning and sanitization in our fulfillment center. With the new government guidelines in place, we hope to be back to normal sometime in May. For additional details, click here. Show More… Show Less…

Stainless Steel

The Super-10 Series mufflers from Flowmaster take the sound and performance of traditional Flowmaster mufflers and turn it up to 11. With a short, single-chamber Delta Flow design, it is as close to running open pipes as you can get. Each Super 10-Series is made from 409S stainless steel.
