Hi I’m Justin with AmericanMuscle.com, and I’m going to be breaking down a system from Pypes they call “The Beast” fitting all 99-04 Mustang GTs. This system is actually a combination of a couple of different parts, first up we have Pypes’ violator series catback, paired alongside with Pypes’ offroad X-pipe. We used this exact system on our 98 bolt on build up, and let me tell you, the beast is a great description of the sound you get using this kit. Both the X-pipe and the catback are constructed using 409 grade stainless and feature mandrel bent 2.5” tubing, through those stainless violator mufflers, and all the way back to these 3.5” polished tips. Since you will be installing an X-pipe along with the catback portion, the install itself will be slightly longer at about 3 hours from start to finish, when it’s all said and done. Of course this factors in time for cutting off your factory exhaust as well, which will need to be done in order to perform this install. Now let’s hear how the beast from Pypes sounds compared to our factory exhaust.

Exhaust Installation any reason this would not fit a 2001 Bullitt, manual trans?

wickman

  • As the Bullitt is a mildly modified GT, this exhaust should not have any fitment issues for your application.

Do i have to use the tips? Do i have to use the tips that come in the kit or can i use different ones?

Mike1die2hard3mustang4fan

  • Looking at the Pypes web page, the tips are described as "slip fit," which would indicate they are not welded to the tail pipe. You should be able to use other tips.

    THE BEAST

    I installed this on my 02 GT and like it alot. if your not looking for a really loud system dont go with this. because its loud... really loud. the kind of loud that draws attention. when i installed this i also did a sct tuner with a bama tune for my car. and it was awesome. probably the funest part is people giving that what the hell look as you drive by. because like i said its loud. only negative is the x pipe hangs lower than the rest of the car. my car is lowerd so speed bumps are a little scary these days. but oh well its still awesome.

    MEAN SOUNDING STANG

    Great product, fit was perfect! Absolutely love the angry sound my stang has now! Only hard part of the install on my 04 GT was the manifold bolt on the passenger side (pain in the @$$ to get off and back on. Other than that two rookies were able to fit the system perfect. Also, don't forget to get O2 extenders!! Thanks AM for kickin' @$$ and having the best deals!

    THE BEAST

    Absolutely amazing sound at full throttle! Only thing is its a pain to install and Im not sure if it was just me but it it seemed to not fit right, especially the x pipe. i had to get it welded but i would probably buy it again just for the sound!

    Great exhaust.

    It just sounds awesome. It sounds like thunder going 60 to 65 mph down the expressway. Even at idle it sounds great. Would recomend this to anyone who wants a great sounding system.

    Great Sound

    The system sounds amazing once it is connected fully. I had to remove the stock studs out of the stock manifold on the driver side and use bolts to get it to fully seal (also, use the insert provided!!!) To do this I used a lift to get under the car comfortably and used a stud remover, one of the studs broke off flush but luckily I was able to drill it out without having to remove the manifold. Once it was on There was some bending involved and cutting, fitment was not very nice. But once the modifications were made and it was in and had good clearance all around it really does sound amazing.

    pypes sound is definitely unique

    I replaced my flowmaster / magnaflow exhaust with the pypes beast with cats designed for shorty headers even though ive got long tubes. With some patience during installation the pypes rewarded me with a beautifully "unholy" sound at WOT.
