Signature Series is HERE!

Premium Materials
Flowmaster’s Signature Series Exhaust Systems are made from high quality brushed 304 stainless steel and paired with black chrome exhaust tips. These systems are also TIG welded right here in the USA. Tig welding provides a stronger and more precise weld.
Exhaust Tone
Signature Series mufflers offer an aggressive to moderate performance exhaust tone and increased performance over stock exhaust systems.
Dyno Proven
You can expect to see horsepower gains from 5 to 21hp and torque gains anywhere from 5 to 26lb-ft over stock.
Fitment
Signature Series is launching with mid and full size truck fitments. Available for GM 1500, Ford F-150, Ram 1500, Ford Bronco and Toyota Tacoma.
More Fitment Soon
Late model muscle cars and additional mid-size truck fitments coming to Flowmaster soon.
