Put one of these on my v6. Pretty happy with it. hardly any interior resonance and NO "v6 humm" but from the outside sounds beast. I dont think its the loudest muffler out there, maybe for the big boys ...

    Not Bad

    Put one of these on my v6. Pretty happy with it. hardly any interior resonance and NO "v6 humm" but from the outside sounds beast. I dont think its the loudest muffler out there, maybe for the big boys it is, but its great for the price. I was worried that it might sound like a ricer on my v6 but it really doesnt at all. I mean, its no v8 dont get me wrong, but it does sound beefy. A lot of people have complemented me on it and it sounds great when you rev it. No noticable HP gains, but you shouldnt expect that from just a simple muffler switch anyway. I would recommend if you're on the fence, excellent price for what you get.

    pypes violators

    the violators do have a nice sound but they have a absolutely horrible humming drone at certain rpms like super high pitched and i have my exhaust welded . welds were a little on the iffy side. would reccommend magnaflow magna packs over these.

    Pypes, great bag for the buck

    If your looking for a great sounding muffler that you can live with theses are the mufflers for you. I had a shop that a friend ownes install them. Fully welded in so no raddles. I put these on my vert and they are great. Loud when you want with a great sound but not droning while driving with the top down. When cruising they are slightly louder than stock but with a little pressure with the right foot they open up and everyone knows its not stock. I couldn't ask for a better performing , sounding muffler that the Pypes Violator. Plus they are full stainless steel so they will last. Look no further than the Pypes Violator.

    Best exhaust for a 4.6L

    These mufflers make my 2000 gt sound like an absolute beast. Its reasonable quite when just driving but the second you give some gas it unleashes the animal. It sounds better then any other car on the road.

    Great exhaust for any mustang!!

    This exhaust is amazing it sounds great and looks great. It is definately worth the money. If you want that great deep sound and love the raspy sound of a mustang then this is for you this is the best of both worlds. No question about it this will give you that off the wall sound even on a stock car. I have never had this many compliments on my car until I got these.

    very impressed

    I bought these for my '97 GT and had a muffler shop weld them on (im not the best welder in the world). They were very quiet when i first got the car back but have progressively gained a but more volume and much better tone. Setup right now with stock manifolds and stock h-pipe and it sounds great if you just want a more throaty tone... but if you want LOUD, add an off-road midpipe

    Not Impressed

    I was looking for a muffler that was not obnoxiously loud but not too mellow, something right in the middle. I listened to the exhaust sound clip and was impressed so I decided to buy these mufflers for my 1999 Mustang GT. After installation, I have to say that I am not impressed at all. The sound comparison isnt even close and to be honest these mufflers arent much louder than the original ford mufflers. If you want a muffler with an aggressive sound but not obnoxiously loud, look elsewhere, if you want a muffler that doesnt sound much better than factory, than Pypes Violator Mufflers are for you, Sorry!

    Great sound

    Great sounding mufflers. Really can't say how much of a power increase they gave me, because I also did a PI head swap and headers at the same time and I haven't yet put it on the road still waiting for a few more things to be done including a tune.

    Pype violator mufflers

    I odered 2 of these for my 89 mustang gt to replace my flow masters. I am running long tube headers and off road x pipes. Along with a mild cam and so many other performance parts. The car has 450hp. I wanted something louder. After reading a ton of reviews on a few different mufflers and watching countless of videos. These violators sounded like they would be the loudest. Needless to say, I was highly disappointed in the sound. The also didn't have the popping noise they say they had when decelerating. No roar at all at crusing speeds. Rpm have to be at about 5 to get a decent sound. Just a few other disappointment. I was excited to get these on the stang and hear the loud rumble and roar. Only to turn around and be extremely disappointed and upset. I wouldn't recommend these to anybody

    Perfect Sound

    Okay to start off, this muffler is amazing and was just what i needed. I recently added a new mustang to my collection. it is the first v6 mustang i have ever owned and i wanted to make it sound more aggresive, but the challenge is that i live near the city so it couldnt be too loud and this was perfect. The shipping was also very fast. THANKS AMERICAN MUSCLE

    Great sound

    Sounds great. I was so tired of the flow master drone I've heard for years. My car came with a pypes o/r xpipe so I decided to go with these mufflers and the combo is great

    Improving a Mach 1 sound

    I realy like the mufflers however if I would have known they came polished I would rather have them. The mufflers came with a 2 1/2" inlet & 2 1/2" outlet which is the same as my tail pipe I just cut a 2 1/4" pipe 2 1/2 " long, I put half into the muffler and half into tail pipe and clamped my band clamps over each , not a big deal worked great. Still the quality of the mufflers is great.

    Raspy Crackle

    I paired these up with an off-road h-pipe on my '97 GT and was very satisfied. They have a very aggressive and raspy tone with that signature crackle when you ease out of the accelerator. The fit to the stock tailpipes was a bit of a hassle but the end result was exactly what I was looking for. These Pypes are mean and definitely have bang for the buck.
