Flowmaster Exhaust Systems

Replace your worn-out exhaust and upgrade to the latest high-performance technology while you’re at it by choosing Flowmaster. The company was born in 1982 in response to growing complaints about engine noise at race tracks, especially from Sprint Cars. By successfully cutting noise without cutting performance, Flowmaster ushered in a new era of performance automotive exhaust systems. Now part of the Holley auto family, they continue to push exhaust technology to the limits for racing, street cars and those who want to customize their rides.


High-Performance Mufflers

The aftermarket mufflers that first made Flowmaster famous remain their leading product to enhance your ride. Eastwood offers the original 40 series high-performance muffler in several sizes to fit your tailpipes. Each muffler is made of 16-gauge aluminized steel or 409S stainless steel that is fully MIG welded for added durability. And while Flowmaster got its start by reducing noise, you now can enjoy an aggressive sound with excellent exterior and interior resonance that will get you noticed on the street, at the drag strip or when you’re off-roading.


American Thunder Exhaust Parts

Make every part of your exhaust system flow to the max with Flowmaster American Thunder header and tailpipe kits. In addition to general exhaust parts, they also make vehicle-specific systems for restoring or upgrading. The Flowmaster American Thunder system is available for the Chevy Camaro, Ford Mustang, GM C10 and other classics. Choose from header-back systems, crossmember-back systems, single-exit exhausts, dual-exit exhausts and other designs. They are a direct OE replacement that gives you even more eye-catching horsepower and ear-catching sound.


Turn Up the Energy

Your car will never feel tired when it has the best Flowmaster exhaust and muffler systems. Everything they sell comes with a three-year limited warranty for your peace of mind as you hit the throttle. You’ll also receive lifetime technical support from the Eastwood DIY experts who are here to help you do the job right.
