Your cart is empty.The Super 50 series muffler is a larger version of Flowmaster's 50 series Delta Flow muffler. Originally designed for trucks and SUV's, it is also well suited to muscle car and high performance applications. In addition, the larger case size significantly reduces interior resonance and provides a deep, rich tone along with mileage and power gains. Constructed of 16 gauge aluminized steel and fully MIG welded for maximum durability.

Fit great on my 2011 tundra. Ended up having to customize the 3" out but worked out great and brought it out the side in front of the rear tire.

Cold start is noticeable. After that, I couldn't tell the difference at the idle, but when starting accelerating, I could hear the growl and rumble. There is a slight drone when cruising around 1.6k RPM but acceptable (my ears are sensitive), and once it revs higher to 2k RPM, its gone. All and all, great!

1999 GMC Yukon (2WD) 5.7 - Totally Stock (Except for the muffler)After extensive research and many clips on YouTube, I decided on the Flowmaster Super 50 SUV because I wanted all the deep, throaty growl the Flowmasters are known for, but less volume and NO resonance at cruising speeds. That's exactly what I got. If the Flowmaster 40/44 series is a "10" on the volume, this is a "7.5". Smooth, deep rumble at idle and a throaty growl when you push it.I've also noticed there is none of the "Cackle" when the RPMs breach 3k like the 40 Series does with some engines. This is a HUGE muffler and is nearly identical to the OEM on the 99 Yukon. This, I believe, is partly responsible for the deep tone this muffler maintains throughout the entire useable RPM range. And, just like Flowmaster claims about the Super 50 series, I haven't noticed any cruising resonance at any speeds (up to 70, so far).Overall I can completely recommend the Flowmaster Super 50 SUV/Performance muffler. It releases the 350 cubic inch muscle without putting a bullhorn on it.

Replaced stock muffler with this 50 series and it is perfect. I was looking for a little rumble and power but nothing to blast my neighbors or be annoying at highway speeds. At idle its relatively quiet. This is the ticket. Overall my truck feels more powerful and tighter. I spent $70 on installation and it's worth every penny. Highly recommend it. My truck is a 2012 Toyota Tundra crewmax V8 5.7 liter. It does the engine justice. LFG!

I love the sound of the Muffler, but it wasnt an easy bolt on for my 97 Silverado. The diameter was different, and the distance between the 2"in" pipes was way off. I ended up having to take it to a muffler shop to have it welded in. It was still cheaper than buying the muffler from the shop that did the welding, but I do wish Flowmaster would make model specific mufflers, or at least adapters.

pretty disappointed in this muffler. The sound was good. Not too loud, not too soft (of course that is subjective). However, i am completed unhappy with the fact that the entire muffler rotted to pieces to the point that the entire back outlet blew out 3 years and 3 months to the date of install. 3 months past warranty. This was worse then the cheap mufflers. You might think 3 years isnt that short, well, it is. Not only that, i had this put on right before the pandemic, and i drove a total of 9k miles over the last 3 years. So tell me, why in the world did it rot so fast?I was always a lover of flowmaster, but i will never buy from them again. What a shame. a picture will attach this review once its removed and replaced with a different company's product.

Used this on a 98 explorer 5.0. Deleted the two down stream cats and dumped at the rear axle. Real happy with how it sounds. Aggressive sound, not obnoxious or annoying on the highway.

Installed three months ago, and seems to be doing well. I'm pleased with it.My mechanic meantioned no issues with the fit of it on my vehicle, so I'm assuming the installation was easy enough.

The fit up wasn't that great and it didn't perform as expected. Nice sound on take off but loud at highway speed

Muffler is a deeper sound but only slightly louder than stock. If your after deep and louder I’d recommend a Flowmaster 44
