And, Flowmaster mufflers go above and beyond your expectations when it comes to improved gas mileage, torque and horsepower.

    Made for your year, make and model (may require modification during installation), these Street Performance Mufflers by Flowmaster also reduce heat and other stress factors on your engine. What's more, your new Flowmaster is backed by a 3-year warranty on the aluminized steel mufflers, and a limited Lifetime Warranty on the stainless steel mufflers.

    I really like the super 44's I bought for my cobra. They give it a good deep growl. I like the quality of the mufflers.

    Tundra -Flowmaster 50 series SUV mufflers

    The 50 Series SUV muffler sounds great on my 2013 Tundra 5.7ltr. Not at all loud or intrusive. Only a nice low rumble reminding you that your rolling a V8. There is little to no interior drone at cruising speeds. My gf didn't even notice until I told her I had it installed. The last thing you want when driving a classy Tundra is to sound like a redneck. Thats what F150's are for!

    ECO ruins it.

    The mds function ruins this muffler. It intensifies the lag and makes the truck almost shake with the addition of this muffler. Ram needs to fix the issue.
