GREAT and WELL MADE in the USA!
These car parts are always for my son. He came and showed it to me. I would have taken a photo if I wasn’t talking on the phone. I’m an artist. My father was a top welder. This item was a beautiful creation and made in the USA. Of course my son also bought it for the sound which he described as quiet with maybe a little pur. I haven’t really heard it. He said it was great. We have someone who just welds mufflers. He is on to the next project. He’s kind of OCD, well, just likes everything perfect. I noticed it was shorter than many. Not that I spend my time under a car. He put it on a 2003 Chevy S10. I always say the trucks begin their best life when my son get them.

Worth the cost
Put these onto my 2013 Explorer replacing the original factory mufflers that had seen better days. They fit perfectly, sound great and is doing exactly what I wanted them to do.

Deep rumble, not too loud
I had two of these installed on my 2008 Audi S4. The sound is deep and adds a nice growl to the 4.2 V8. They are not loud but do make the car sound more alive, especially decelerating in lower gears. I’m a fan

Good power gains, but WAY TOO QUIET!!!
I have to give a good review because of the fantastic quality these mufflers are, but THESE THINGS ARE WAY TOO QUIET!!!! I installed a Magnaflow x pipe and deleted the cats on my '08 crown vic when i installed these mufflers and removed the stock exhaust. I read the reviews thinking they would sound nice and be a good volume, but wouldn't be ridiculous. DON'T BE FOOLED!!! They sound great, they do, but they aren't much louder than my stock exhaust, I'm not sure if its the muffler's fault but I feel like the only reason it is only a little louder is because i removed the cats. So, Im disappointed that I spent so much money on two of these and an x pipe (around 400 dollars) and it sounds no different. I even compared with a decibel reader, and these mufflers are only 3.5 decibels louder, if that. If you want a nice sound, louder than stock, but not obnoxious like cherry bombs, Id recommend Flowmaster 40s. But if you want a good gain in performance but want it quiet (maybe you have a sleeper build in mind) get these mufflers.Idk what people were saying how these are "way too loud" like they sound just like stock.......Also, I do feel like the flow has been freed up, by a lot. you can look down these mufflers and see through them, they have it flow very well, again, also thinking that they would sound loud, but they dont, but these straight through style mufflers with the x pipe have picked me up like 10-15 hp, with a good brand intake you could see some nice hidden power from your engine without attracting police. So enough of my rambling, still 4 stars because they are good, but I hate that they are so quiet, quite a disappointment.... :(

Nice sounding muffler.
The media could not be loaded. Sounds amazing this is with just the muffler, it’s deep but no to loud to be annoying. This my 2010 Honda accord coupe 2.4L

(Relatively) Quiet Performance
I just installed this on my 1996 Honda Del Sol which has a full exhaust that originally came with a N1 -Style Canister Muffler. Regardless of having the top on/off, windows up/down, the old muffler was LOUD to say the least. Worst off all, I could not really hold a conversation inside the car and I looked like an idiot taking off from an intersection as everyone thought I was trying to race them! :\I am huge fan of magnaflow, but looked at other products first, including the complete Dynomax product line. I wanted something quiet that would not hurt performance (Don't we all). After roughly calculating the required flow my engine would need, I ruled out the Dynomax Super Turbo (regarded as one of the most quiet performance mufflers). The Dynomax VT looked good, but I found many (online) reviews of issues with the diverter valve and spring assembly. The Dynomax Ultra Flo is most like the magnaflow, but costs more.This muffler has a high flowing straight-thru design that does not hamper performance. Best of all, the noise level of this muffler on my car is almost stock. It has a really mellow tone that wakes up under hard acceleration.I am extremely happy with this muffler as it solved my loud exhaust issue with a quiet, high flowing solution.
