Flowmaster 40 Series Chambered Muffler – 3.00" Center In / 2.50" Dual Out

Very easy to install yourself, trusted brand that sounds great!

Did the job, I'm very impressed how it sounds on my particular vehicle, I was worried about it sounding like a fart can but it definitely is far from that. I definitely recommend flowmaster if you like a nice deep rumble

Excellent product from a exceptional company, sounds amazing

Exactly what I was looking for

Installed this on my 2015 Hemi Dodge Ram. Sounds fantastic. Throaty and aggressive but not overwhelmingly loud. I wanted something that just let me hear that Hemi without pissing off the neighbors. With this muffler you need a single 3” pipe (I think it was 16 or 18” long, bought from pep boys for $16) and two 2.5” couplers that step down to 2.25” (2.25 is a the stock exhaust pipe size after the muffler.) I’m a very amateur welder, with an amazon special $100 mug welder, but I welded them on after mocking it up and tac welding them in place, then you can fully weld off-vehicle. Then all I had to do was use one 3” band clamp and two 2.25” band clamps to put it on. Whole process took about 3-4 hours because I’m slow. Would buy again.

Love the sound

Like new in the box, i was worried do to it being a return, however, it was just what I needed. Thank you Amazon and seller.

I was looking for this in a 3inch dual out but the 2.50 definitely does the job. I think its definitely gotten louder since I bought it a month ago, some people may disagree. Not too bad on inside drone..You can hear it the most around 1700-2000 RPM, pretty much right before it wants to shift or at about 77MPH. I bought this for my 2002 chevy silverado 1500 5.3l V8. If I did this again though I would make my exhaust true dual and still use the 40 series

Fits good on a 2017 Ram 1500. Nice tone to it .not as loud as the super 10 that was on it but still sounds good.

Like always, Flowmaster makes a great product. Very happy with the sound and lil extra ooompf from their exhaust systems.

Sounds great on my 5.7 ram

I have a 2017 Ram 1500 with 5.7 Hemi with factory dual exhaust. I ordered this muffler on a Monday, was expected to be a week before delivered. I was stoked to see it was delivered by Friday afternoon before I got home the same week. I did leave the resonators on so all I did was had muffler swapped. Only thing you can hear a little now and then is when it kicks MDS in. It's a small trade off for that nice growl and rumble out the back. Had it installed this past Friday at a local shop where they had to make a couple custom pipes so it would fit properly because the factory muffler is 2x the length. This muffler makes that Hemi sing 😍 a good tone at idle and start up and let's me know it's there when I'm getting up to highway speeds. Overall very impressed with delivery of this item from the seller and the performance and sound my truck puts out with this muffler. I will definitely buy again in future if needed.

Good product and very accurate discrimination A+++
