Much better then I expected.

Bought for my 91 LX, this catback is mated to a BBK H-pipe, chrome BBK long tubes, which is coupled to a 347. I am extremely please with this cat back. I bought it instead of the other brand that AM sells

Will this exhaust system fit with my BBK long tube headers I am wanting to know if this exhaust system will fit my 2003 mustang gt. I have a 4.6 SOHC V8 with BBK long tube headers. Will the pypes exhaust fit with out any adjustments, or cutting.

  • You will need the correct BBK H-pipe or X-pipe to match your long tube headers. If you already have that then this cat-back system will fit just like any other cat-back system.

Answer This Question

Replacing the mufflers How hard would it be too replace the mufflers on this system, as they have a slight angle on either side, & differ from the M80's sold Individually ?

Hessian5k Year: 2003 Model: GT

Good Question (0) (0)
  • Yes it will be replacing the mufflers if they are behind the cats, in which most cases they are.

    Much better then I expected.

    May 05, 2013

    Bought for my 91 LX, this catback is mated to a BBK H-pipe, chrome BBK long tubes, which is coupled to a 347. I am extremely please with this cat back. I bought it instead of the other brand that AM sells since it is basically the same thing but this one was actually in stock and $100 cheaper. All I can say is wow! I never expected it to be so good. I had the typical Flowmaster cat back that the previous owner installed. It was old, rattly, and rusty. Since I had the car apart for the LT's and H pipe I decided to do the cat back as well. Fitment is better then i expected, the all SS construction is very nice, the over axle tubes were slightly oval'd which made mating up the mufflers a challenge, nothing major though (installing exhaust is always tough without a lift). As for the sound, the drone I had from the Flowmasters is gone, the idle is super deep, it isn't too raspy, and the overall sound is better then I could have hoped for. Definitely give this CB a strong consideration if you are looking for a replacement for you current system.

    Impressive Quality

    May 23, 2013

    I bought this kit for my Mach 1 and was very impressed with it the moment I took it out of the box. The level of craftsmanship was much more than I was expecting. The welds looked good and the entire kit come polished to a brilliant shine. Installation was a pain in the a**, but that is to be expected when installing an exhaust system of any sort without a lift. The most time consuming part was getting everything to line up properly. I found that what worked best for me, was to first focus on getting the mufflers tucked up as high as possible, then make the final adjustments at the tips. After doing this, the ground clearance is excellent. Both mufflers sit about flush with the factory sub-frame connectors. The only issue/complaint I have with fit and finish is that I was not able to get one of tips to fully cinch down on the pipe, allowing it to move around while driving. I plan to have everything finish welded at some point so it's not too big of a deal, but still worth mentioning. Finally, in terms of driving experience, simply astounding. My car sounds incredible from idle, all the way up to 6,800 rpm. I was also surprised to find that there was no noticeable drone at highway speeds. Next up: long tubes and O/R X-pipe!

    1996 Mustang GT

    May 05, 2013

    I chose this product because I had been happy with the purchase of my O/R X pipe 2 years earlier (which still looks almost new). Well this did not disappoint at all... It bolted right up with minimal problems and looks perfect...The sound is amazing and its has a nice rumble when driving which is not to loud( passed a cop no more than 2 min after taking it out) but when you get on it, it roars...really throaty/mean sound...nice to drive/hear a mustang w/o the usual chambered muffler sound

    Great Tone

    May 18, 2013

    This catback exhaust kit by Pypes has a great deep tone that sounds great when on the throttle. The sound is just right, not extremely obsessive but has just enough tone to let people know you're coming. After I took my time to set the system it turned out great, with the 3.5 SS tips out the back everyone notices.

    Love this exhaust

    October 18, 2013

    From the moment I bought this exhaust I have loved it! It isn't quiet, which is pretty much what I was hoping for. When my car was N/A it gives it a real muscle sound that I have been looking. Sounds even better now with my turbo. Definitely recommend.

    Great Product!

    August 26, 2013

    This exhaust is just unbelievable, I've put it on my 2002 V6 with a X-Pipe and WOW what a difference! The raspy sound give me a huge smile every time I take it up to 3000-3500 rpm. And the look is awesome, dual exhaust is way nicer than the original single one. Thanks American Muscle to provide me this great product in a short time.

    I purchased this catback for my 02 v6 not knowing what I was getting into, I had heard some v8's with it but I knew my six banger would not sound the same. I took it to a local shop and had them install an h-pipe from pacesetter along with it. (Keep in mind my mustang's exhaust was stock). Installation was about two and a half hours, and the sound was instant. It seriously sounds like a v8, and I've had 2 people asking me if it was. Idle is fairly quiet but as soon as you step on the the throttle it roars, and is mild when cruising. Definitely recommend for any kind of driver. Other mods: SR CAI

    let me first say i was skeptical about putting this exhaust on my car. I'd heard a Coyote mustang with it and i loved it and then heard another mustang with it and didn't feel the love and besides, i like a more "mature" and refined exhaust note. The actual install of the exhaust was amazingly simple. the hardest part was removing the old dynomax exhaust from under the car. One i cranked it up i was shocked, there was no loud booming exhaust note, just a muted muffled rumble that was barely audible (mind you i have the stock H-pipe and stock manifolds) Drove the car around for awhile with the windows up and down and it is the most peaceful exhaust I've ever heard on a mustang. There is absolutely no drone whatsoever just a smooth tone with a subtle hint of the '68 Bullitt Mustang. If I'd had the radio on i don't think i would have heard it. I love driving my car again. I do recommend this exhaust to anyone with a factory H-pipe looking for good flow without noise!!!! To Pypes, you have exceeded my expectations!

    good not great

    July 24, 2013

    every thing is straight forward nice looking and good sound, only thing is tips do not clamp all the way down and move on pipe. and still waiting after a month for new tips from pypes, so if you have problems don't hold your breath waiting for pypes to get items to you.
