        Love them

        I bought these mufflers and the Pypes off road x pipe and installed them together and it's exactly what I was looking for. 99 gt sounds like a mustang v8 should. Not too loud when cruising and when you floor it, it sounds amazing.

        Amazing value

        I have owned my 1999 GT since new, and have tried many exhaust systems in that time. These are by far my favorite, and have such a unique sound. If you are looking specifically for the Flowmaster sound these are simply not for you. (IMPORTANT) I understand there is no "burn in" period for these mufflers, but my own experience and those of others confirms the sound these make when first put on is tame compared what they sounded like after a month or two. So no matter what ANYONE tells you there is in fact some sort of break in period where the sound changes. Most notably they did not have the awesome popping an crackling when downshifting at first, and this took at least a couple of weeks and a few hundred miles of driving to develop. So no they are not as loud as the Flowmaster 40's inside the car, but outside the car everyone hears you just the same. Best of all when cruising at lower speeds, you can chose to be heard by keeping it in a lower gear and running in that sweet spot around 2000 RPM, or drive in the higher gear keeping it around 1200-1400 save some gas, and arrive in stealth mode so that no one hears your awesomeness until you are right on top of them. On the highway in 5th gear my GT with stock gears is not overly loud right around 55-60 MPH and fine for long trips you can't talk at normal volume and hear the radio. However it turns into pure beast mode between 60-80, it sounds AWESOME, but on long trips at higher speed it could be deemed "annoying" by some. I want to emphasis these really do have a unique sound that is quite different from the "Flowmaster sound" which ever other muffler seems to emulate. It's admittedly not as menacing as one of the more aggressive Flowmaster series when at idle, and inside the car it's not nearly as loud, but under WOT or when raving it up in the parking lot, the sound is pure bliss and flat out nasty. If you are one of the people crying this or that is not "loud enough", as if loudness alone were the only measure of how "good" and exhaust note sounds. You should probably be driving a 4 bangger with a hairdryer, no cats, and a coffee can hanging off the back. If you want the ultimate tone that will not ruin your hearing, and sounds flat out nasty when you rev it or are WOT these are the ticket. You could probably slap these on in hour or two, but if you are using new flow tubes, and want to cut everything to make the tips flush with your rear bumper. Give yourself a day and have it look like a pro did it.

        Pypes Violator Mufflers - nice!

        I just had these installed yesterday. They went into a completely stock exhaust on a 95 GT, as the stock exhaust was way, way too quiet for my taste. The sound from these mufflers is just what I was looking for. They are quiet, but with a deeper rumble, at idle and below 2500 rpm. Then they start to open up, but even then they are deep and throaty without being obnoxious. The only installation issue was my stock pipes were 2" and these had 2.5" inlet/outlet. The shop that installed them had no issue with that, but it cost me a few extra bucks.

        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
