    Deep throating growling muffler

    Love Flowmaster mufflers, I've had them on 4 of my cars and trucks and was always satisfied with the results. Especially on my most recent purchase of the 40's that I put on my sbc Nova the sound is like no other. I love that deep, throaty, deep growling sound and not so loud on idle and no drone sound in the car. I would highly recommend these mufflers to anyone looking for that same sound

    Flowmaster 40

    Purchaced a flowmaster 40 muffler years ago for my dodge van with a slightly worked magnum 318 and a high flow cat when my stock cat went bad,,, The sound is exactly what I was looking for deep and throaty,,. Also helped my speed on the top end and helped the motor breath easier,, you will not be disappointed with the flowmaster 40 muffler,,

    FLOWMASTER the sound of muscle.

    Great sounding muffler,nice throaty muscle car sound.Original 40 series sounds better than the super 40 series muffler.Price not bad considering the competition out there.

    Always loved the flow master sound. You can’t beat it. I don’t know why they are black now. Kinda looks ugly.

    Sounds great

    Anyone with a 4.3 vortec I would highly recommend this muffler! It doesn't have the high pitch at higher rpm's! Has a nice growl at idol!

    Excellent, super deep rumble from a Ford truck

    The sound exactly like you would expect the original Flowmaster 40 to sound, very deep rumble, no rasp whatsoever
