Best Car Exhaust Mufflers of 2026

"After installing this on my truck, I noticed a deeper, more aggressive sound and much better throttle response. The build quality is top-notch, and it really helped my engine breathe. The only minor downside is a bit of cabin drone, but that could be my setup. Overall, very satisfied with the performance boost."

"I was impressed by how much quieter my car runs now without losing any power. Installation was straightforward, and the fit was just right. What stands out is the significant noise reduction and no rattles or unwanted vibrations. Definitely a smart buy if you want a quieter ride without sacrificing performance."

"I put this on my Ram 1500 and the sound is exactly what I wanted—deep and mellow at idle, with a great tone when you hit the gas. There's a slight drone at light throttle, but it's very manageable. For the price, you can't beat the quality and performance."

"After installing this muffler, the obnoxious noise from my straight pipe exhaust is finally gone. The drone is under control, and I can still hear the turbo whistle, but it’s much more pleasant. It fit perfectly, looked good, and the metal was sturdy enough for a solid weld. For the price, I’m really impressed."

"My 6.0 Powerstroke Excursion with a straight 4-inch exhaust was just too loud for daily driving, so I swapped in this muffler. The difference is night and day—now the engine is the only thing making noise, and the exhaust is just a faint, muffled sound. Installation was a breeze. This is exactly what I needed."

"I was skeptical at first, but after putting this muffler on my deleted 6.7L Powerstroke, it’s been incredibly quiet in the cab—almost too quiet! For the money, it’s been totally worth it, and the install was straightforward with plenty of space under the truck."

"I installed this muffler on my truck and I’m really impressed—the fit is perfect, and the sound is deep with a nice rumble. At highway speeds, it’s quiet with barely any drone in the cab. I’d definitely recommend it to others looking for a quiet yet strong exhaust sound."

"After several months with the FlowFX on my 2003 Tahoe, I found it’s louder than stock and has a mellow, smooth sound, which is different from the typical tinny Flowmasters. The drone is noticeable but not overwhelming, though it might bother some on longer drives. Build quality is solid, so if you’re after a mellow tone and don’t mind a bit of drone, it’s a great choice."

"I put this on my 4.7 V8 and it’s noticeably louder than stock, but not too much—just a smooth, deep tone. I’ve even seen better fuel economy since installing it. For the price, the sound and performance are amazing."

"I put this muffler on my '93 Celica GT as a temporary solution, and honestly, I’m impressed with how much it cleaned up the sound compared to straight piping. Installation was a breeze with a clamp and a pipe extension, and the chrome finish looks fantastic after a quick polish. I noticed no droning on the highway, and for the price, you really can't beat it."

"After installing this on my car, I was blown away by the deep, throaty growl it gave my exhaust. It’s just aggressive enough without being obnoxious, and the stainless steel construction both looks and feels premium. Whether cruising or revving, it adds the perfect amount of attitude. Highly recommended for anyone wanting to upgrade their exhaust without breaking the bank."

"I've tried several mufflers over the years on both V6 and 4-cylinder engines, and this one is hands down the best for the price. It eliminates that annoying trumpet sound on V6s and the rattle on 4-cylinders, replacing them with a nice, deep tone. Absolutely amazing value and quality."

"I put it on my Camry and it definitely gives a turbo-inspired sound, which is what I was looking for. The installation was simple and the price was right. It's not super loud inside the car, but it does give that little whistle outside."

"Honestly, I was pretty disappointed. The sound is too subtle and doesn't really mimic a real turbo. Plus, the quality feels cheap—mine even fell off after just one drive. I wish it was made to last longer."

"I was expecting something a bit more noticeable, but the noise is barely there and it doesn't sound like a real turbo. It's not a total waste, but I wouldn't recommend it if you want a strong effect."

"I was blown away after installing this on my '07 Ram with a second gen swap. The noise was cut down by at least half, and there’s no more cab drone. Still delivers a deep note without being overbearing. I’ve tried pricier brands before, but this muffler, at a fraction of the cost, is seriously impressive. If you’re unsure, just go for it—no regrets here."

"After hours of research trying to get rid of the highway drone on my 2022 6.7 Powerstroke, I decided to try this muffler. The difference was immediate—quieter idle and completely eliminated the drone. The stainless steel matches the rest of my exhaust, and for the price, the value is unbeatable compared to more expensive options."

"I put this on my F350 with a straight-piped 4” exhaust to tackle the unbearable drone at highway speeds. This muffler eliminated the drone completely while keeping the exhaust sounding great at idle and wide open. Honestly, you’d have to spend a lot more to get the same effect, so I highly recommend this over big-name brands."

"I absolutely recommend this turbo whistle! The quality feels great, it was easy to put on, and it instantly made my car sound sportier. For the price, it's an awesome way to upgrade your ride without breaking the bank."

"I've worked as a mechanic for decades, and after installing these XL Turbo Whistlers on my BMW, I didn't get any noise at all, even though I mounted them securely. It's frustrating because I expected a noticeable sound, but it just didn't deliver for me."

"The whistle looks well-made, but it doesn't really work on every car or with every exhaust type. Most of the time, you can't hear it, or if you do, it's just a constant high-pitched whistle. Maybe a larger size would fit better and work as intended."

"I bought this for my '97 Jeep Grand Cherokee and was impressed with the quality. After installation, my Jeep became noticeably quieter, which was exactly what I wanted."

"Opting for this Walker muffler saved me money compared to online alternatives. The installation was straightforward, and with a little mechanical skill, I had it fitted in no time. Just be prepared with the right tools and clamps."

"Although the product was advertised as a direct fit, I needed additional adaptors and clamps since the sizes didn’t match perfectly. The extra cost and time were a bit frustrating, but at least I got the muffler installed."

"I got this because I wanted my car to sound cooler, and honestly, the whistle noise is hilarious. It’s definitely more of a fun toy than a serious turbo sound, but I enjoy using it to mess with friends or just for laughs."

"I put these on my car as a joke, and installing them was pretty simple. The sound wasn't as loud or turbo-like as I expected, but my daughter actually thinks her car drives better with them, so it’s a win for us."

"Unfortunately, when I tried it on my car, it barely made any sound—just a quick chirp and nothing else. The performance was underwhelming, so I ended up returning it. Maybe I’ll try another one in the future and see if I get a better unit."

"After putting these on my '96 Fleetwood Cadillac Lowrider, I'm honestly surprised by how quiet they are—there’s a low rumble at idle and a mellow tone even when accelerating. The only thing left on my exhaust is the catalytic converters and these Flowmasters, and they’re definitely quieter than I expected."

"I’ve had a pair on my Kizashi for over a year and a half through tough Pennsylvania winters—they’ve held up with no rust. They’re not as silent as my stock mufflers, but they’re not obnoxious either. The idle is quiet but the throttle gets a nice, low rumble—no annoying noises, just a great tone."

"I put one on my 2020 Passat high line, and it sounds awesome—not too loud, not too quiet. If you want your exhaust to have a little more life without going overboard, this is the way to go."
