Best Car Exhaust Mufflers of 2025

"I recently purchased the EVIL ENERGY Exhaust Muffler, and wow, it has completely transformed my car! The deep and throaty growl is music to my ears, turning heads wherever I go. Plus, the installation was a breeze, fitting perfectly with my vehicle."

"I love the look of this muffler on my little Versa! The only downside for me is the drone at low RPMs, but overall, it’s a fantastic mod."

"This muffler sounds amazing! I installed it on my 2.4L Honda Accord without any welding—just clamped it on. I had to add an extension pipe to reach the back of my car, but it was pretty simple overall!"

"I didn't buy this muffler for looks or sound, but to eliminate cabin droning. It worked perfectly for that purpose. However, it's a cheap flow-through muffler, and I noticed some rust after about a year. Still, I’d say it’s worth the buy."

"I replaced the tip of my car with this muffler, and it made the exhaust loud with a low rumble. I love the sound!"

"The quality is impressive, and I saved a ton of money by choosing this over name brands. I really appreciate the burnt tip option—it’s a fantastic cheap alternative for a good sound!"

"I thought it would sound like a fart can, but I was pleasantly surprised by the great sound quality. After hearing it, I ended up buying a second one! On a loudness scale of 1 to 10, I'd give it a 7. It's the best muffler I found here."

"I bought this as a temporary solution, but I was really impressed with how it sounds. It's sturdy and looks pretty good for the price. I didn't expect it to be this nice!"

"The appearance of the muffler is beautiful, and even though I haven't installed it yet, I'm excited to hear how it sounds."

"I found the best price for the muffler I needed."

"It seems to be made of good material and construction, and it works well for my needs."

"I purchased this muffler for a generator, and I wanted something quiet. I've used Walker mufflers before and have always been happy with the quality. This stainless steel quiet muffler is no exception; it is indeed quiet."

"I bought this muffler advertised as a direct fit, but after removing the old one, I realized the pipes weren't the same diameter. It ended up costing me more for adaptors and clamps, making this a frustrating experience."

"For my 2012 GMC Terrain, this muffler was a good fit. Just remember to purchase the clamps separately, as they aren't included with the muffler."

“I thought it was great, but it fits in my car maybe not the way it was intended. One thing I found misleading is that it sounds more like a whistle unless you're on the highway at high speeds, then it sounds awesome. At slower speeds, it's just a high-pitched whistle, which some people might find annoying.”

“I bought this as a gift for my son's Four-Wheeler, and he really likes them a lot.”

“I feel like this is a scam product. I regret spending my money on it. After researching, I found no reviews confirming these muffler attachments create the sound as advertised. It's a RIP OFF.”

“I mounted these XL Turbo Whistlers on my twin turbo BMW 535i, and they did not make any noise. With 30 years of mechanic experience, I ensured they were securely attached, but unfortunately, they simply didn’t work. I’m frustrated that I wasted my time, and now I have to remove them because they don’t produce any sound at all!”

“Cela réduit l'échappement et le moteur n'aime pas ca surtout a long terme je ne conseille pas en plus siffler avec un sifflet fait pareil …”

"I found that this muffler doesn't significantly reduce noise, but it really does eliminate all the rasp and popping. It works perfectly for my setup, especially since I was able to run two of them in series."

"I installed this 2.5" muffler on my FJ Cruiser, and it really unleashed some power! It has a nice rumble when I accelerate and a deeper tone when cruising. I had to adjust the clamp a bit, but overall, I'm really satisfied with this purchase!"

"This muffler fits perfectly on my 2001 Silverado and was easy to install. The sound is great, and I’m really pleased with how it sounds overall."

"I found a great price for this muffler and I'm overall happy with my purchase. I installed it on my 5.9 Cummins with a 4" straight pipe turbo back. It was loud at first, but I needed to tone it down for family rides. Now, the idle is much quieter and there's less drone, though it still has that bark when I step on it. It was definitely worth the money I spent."

"I had a Flowmaster before, but it created so much drone inside my car that it was unbearable. This muffler fixed the issue! It still sounds loud when I push the pedal, but I can maintain that deep tone without the headache from drone during long drives. I will definitely buy this again for my next project. Trust me, invest in this quality muffler instead of overpriced alternatives!"

"I was pleasantly surprised by this tiny 12-inch glass pack muffler. It gives a shockingly quiet yet resonant exhaust note that makes my old Dodge 4.7L sound incredibly tough. The cabin noise is at a reasonable level, and for the price, it's a fantastic deal. It's built like a tank and has practically ZERO restriction!"

"I've experienced high quality materials that truly impressed me. The customer service was also exceptional, making my purchase even more satisfying."

"For the price, I didn't expect much, but the affordability combined with its ease of use exceeded my expectations."

"I took my 4-inch straight pipe back to stock sound. Now I can talk on the phone and hear the radio again. So much more pleasant!"

"I found the quality to be great and it definitely helped to eliminate the drone when used with a resonator. The sound is low and even."

"This fit my four-door F350 perfectly. It mellowed the exhaust, which was never too loud, and while it didn’t completely get rid of the whistle under full load, it has made it better."

"I installed one on my Chrysler Crossfire, but nothing happened. The second one gave a slight chirp, like I ran over a baby bird. This item is garbage."

"I found it easy to install, but unfortunately, the sound didn't work at all. I noticed a manufacturing issue, and after returning it, I'm willing to give it another shot if I get a better one next time. It’s a shame it didn’t work."

"Using this as a joke for a friend's car was a hit. They worked great, and the price was fantastic!"
