    Review & Installation Video

    Hey I’m Justin with AmericanMuscle.com, and I’m taking a closer look at the Pypes violator series catback exhaust, fitting the 98-04 Mustang GT, Mach 1, and Bullitt. Pypes exhaust systems usually feature very aggressive tones and it’s the same with the violator kit shown here. The name comes from the two violator series mufflers that this entire kit is built around. They actually feature mini sound deflectors in place of the traditional baffles, which will really allow your 4.6 to be heard. As for the construction we’re looking at full 409 grade stainless throughout, including the 2.5” mandrel bent tubing, the violator mufflers, and those 3.5” OE style polished tips. We do have this exact same kit used on our 98 GT bolt on build up, in conjunction with Pypes’ off road X-pipe which they refer to as their beast setup, and let me just say I am a really big fan of this exhaust. As for the install you will need to cut your factory exhaust just to remove it entirely but after that the new Pypes system should install without modification in about 2 hours. Now let’s hear how the Pypes violator series catback sounds compared to our factory exhaust.

    Increase In Performance. Bolting on a Pypes Violator Cat-Back system to a stock 1998 to 2004 GT will yield an instant 8 to 13 horsepower gain. It features two of Pypes Violator mufflers for the ultimate in flow and power gains with an aggressive rude sound.

    Aggressive Sound. Pypes CatBack features the Violator "Rude Sound" muffler that uses an internal louvered tube with mini sound deflector chambers that result of a unique aggressive muscle car sound.

    Quality Materials. This Pypes Cat-Back Exhaust is constructed from free flowing mandrel bent 2.5" 409 stainless steel tubing and features Pypes Violator chambered mufflers for an aggressive throaty sound. The whole system is finished off with a set of 3.5" Polished 304 stainless steel tips for classic Muscle Car styling.

    Application. The Pypes Violator Cat-Back Exhaust kit is specifically designed to simply bolt-on to the existing stock H-Pipe of any 1998 to 2004 4.6L GT, Bullitt, or Mach 1 Mustang for more power and a more aggressive sound.

    Is it compatible with a 01 v6

    Francisco

    • In order to use this Violator Catback (or any other GT catback) on your V6, you would have to install either the Pypes Catted or Off-road X-pipe designed for the V6 or use the V6 Dual Exhaust Adapter Kit. I've attached all (3) options below so you can take a look and decide which would be best for your application. One of these mid-pipes would then allow this or any other GT catback to bolt up without issue! Hope this helps!

    • The Pypes Violator Cat-Back Exhaust does not require cutouts. The Pypes Electric Exhaust Cutout Kit is used to allow the exhaust to exit before the mufflers for race applications.

    • Only headers and catalytic converters are affected by somg tests. If the exhaust you are looking at doesn't involve these pieces then you have nothing to worry about.

    I just ask a question able fitment for my 2003 GT Premium but I read it fits coupe and convertible so all I need to know is about the tips you say the Pypes catback come with 3-1/2 tips which is what I want with the SFM27V other places say 3 in just want to make sure before buying.

    I want to give my 02 GT a more aggressive sound to it and this seems like it, but it is also my daily driver. I'm not much of a mechanic and I want to know will it cause my Check Engine light to come on?

      I had a very old flowmaster exhaust that I loved, for over 10 years till a very bad rock on a dirt road. This new exhaust changes the whole car. She was loud before but now she's nasty. I'm very happy with my purchase. Got here fast and with no damage I couldn't be happier

      Great Pypes! ;)

      This system has a great sound. I love the side by side video clips for sound comparison on the website. It helped me to choose exactly the system I wanted. Got it cheap for Labor day sale and free shipping! I had a muffler shop install it for 2 hours labor.

      Great sound and price!

      I'm very happy with this product. I didn't have to spend a ton of money and still got that deep aggressive sound when I am on the gas. It's as quiet as stock at idle and not bad at highway. Only problem was they sent me the wrong sized exhaust tip but when I called they sent me a new one of my choice at no charge! Even called to let me know when it was coming. I would highly recommend!

      Had flowmaster American thunder was way too quiet and droney, my state laws wont allow an off road h pipe so i opted for something louder, to my surprise these were similiar to the slp loudmouth, from videos i have seen , meaning they scream with aggression and a bit of rasp, i love it very bawlsy sounding. A great system , just one rev alone is like heaven for a muscle car enthusiast, not sure why these aren't as popular as other catbacks seriously underrated. buy it!!

      Love this setup! Loud when you jump on the gas and quiet at idle. Also no highway drone which is awesome! Definitely gives the car a different sound than the typical flowmaster mustang sound.

      Not to Loud

      I just put this on my 04 GT with the stock H pipe it is a little bit louder than stock but not much it is just what I wanted. I did it myself on a hoist but it would have been easier with help holding parts in place and getting everything lined up.

      97 gt violator cats

      This catback system has definitely waken up my ride. Supporting it, i have shorty bbk headers, and bbk h-pipes. Its sounds incredible!! Although louder than i wanted. One thing i was worried about, was loosing that distinctive mustang sound....you know the one..."oh yea, that was a mustang!" I saw my brother on the other side of the median heading the opposite direction. I stomped on it as he passed. 2 mins later in sent me a "lol wow". When i saw him later he said, he heard it and was like "What Was That"!. Looked through his window and saw my car. Thats when he sent me the txt. So yeah, im very happy with this purchase. Yet again, thank you AmericanMuscle.

      When I order this system I had read and listened to many review online and YouTube videos. The sound is ok but what I wasn't happy about was the quality and manufacturing of the exhaust. I wouldn't recommend this system to anyone

      Amazing Exhuast!

      The install part wasn't too bad it took us about 2 hours and it was fun doing it. When we took the car off the jack stands and fired it up, I was instantly satisfied with the product! The nuts and washers the set comes with are awful so go to lowes and get your own or use the factory nut. 10/10

      big improvement over stock

      Installed in less then 3 hours. Fit nicely and sounds great. Not overly loud but enough to give the car the right sound but not enough to be annoying while driving on long trips. Hardest part of install was removing old pipes (rusted bolts) install was a breeze. would highly recommend
