    Mach 1 Fitment I've been looking for a replacement mid-pipe for my Mach and this one seems like it would be a good choice, however, it does not say explicitly that it fits the 03-04 Mach 1 Mustangs, even though many of the alternate pipe systems are interchangeable between many of the different submodels. So will this piping fit my 2003 Mach 1 (manual transmission) or no?

    Blown72Mustang

    • Yes it will, just put one on my 04 Mach tonight. Very strait forward, also 02 sensor extensions are a must.

    Do you sell the Catalytic Converters? I have this setup and the Cats have gone bad. If not where can I get them?

    Will this pass Emissions testing in Utah as the Original Replacement part has four Catalytic Conveters?

    • The Bassani Catted X-Pipe is not compatible with the BBK 1 5/8 " Long Tubes Headers. You will require a matching shorty X pipe with the headers.

      Bassani X-pipe

      Had my mechanic install this part. Took about 45min. Great sound. I love the rumble. Goes well with my SLP Loudmouth exhaust. The cats are higher off the ground than my old "high flow" cats. More ground clearance now. Not bottoming out those pesty speed bumps. That alone is worth the price!!!

      Bassani For the Win!

      This is quite possibly the best sounding X-pipe that I have heard. It installed with no issues and pretty quickly. The hardest portion was removing the factory H-pipe. If you're on the fence about this go ahead and take the dive. You won't be disappointed.

      Bassani catted x pipe

      Had this x pipe on for about a year now. Still cel or any problems all with it. Did notice it was an instint drone maker inside the car though. Have this x pipe with the bassani catback and it still sounds great. Sounds good and doesnt sound obnoxious. Although I would like it to be alittle bit louder it still sounds great. Was very easy to install on jackstands in a driveway. Everything lined up good and is tucked away tight even with lowering springs.

      Bought this 17 years ago. Still good as new.

      June of 2000 I bought my first and only brand new car: My Ford Mustang GT 'vert. 3 days later ordered this X pipe and the cat-back. When they say they're engineered to last, they are not kidding. 17 years and no rust anywhere I or my mechanic can see. And the sound of the system is just awesome. No raspy empty noise, no drone at highway, etc. A nice deep bass rumble and (at least in my ride) a nice burble-burble-burble on decel in gear. It does not need to all-out thunder roar all the time - it gets it's point across at the stoplight just fine with that bass rumble. I had it all installed together, I expect most of the sound improvement is the cat-back but the X, I'm told, changes the sound somewhat also as it's flowing differently, etc. Last word? BUY WITH CONFIDENCE! -JD

      lively

      Came quick, a few days, everything needed except a new left manifold seal ($7 from auto zone). Took some time to get my old stock cats off , so soak the nuts on the manifold well with a thread buster/lube. Take negative off battery so not to make sparks with the starter. New exhaust went in easy except for the far left nut(go through the wheel well, take off the left front wheel); make sure to recheck everything tight when finished. Mach came alive with more torque, pull, life. Best catted x-pipe I could find for the price, great quality. But for me I still prefer the deep thunder of the H-pipe, I needed to wake up my Mach and needed the 20 hp that was advertised, and got it. Exhaust tone is loud, poppy, aggressive and a joy to drive. Total install time: 3-4 hours with no help/novice car mechanic.

      This x pipe is really nice and fits perfectly. It's a little expensive but you pay for what you get. Also sounds really good with or without the cats.

      Fits 2003 Cobra as is

      Packing was robust and can withstand UPS. Fit and finish are above expectation and a breeze to install. No leaks at header or at clamps. For 2003 Cobra, this part fit perfect without O2 extensions or concern. Ground clearance is the same if not better than stock. With cats, exhaust at idle and low rpm is on par with stock if you use the cats. Great product and great site to buy from

      Cutthroat sound, visceral experience

      I ordered this x-pipe about two years ago and mated it with a set of bola stingers. My mustang is just your typical bolt on car, but it sure doesn't sound like it. This Bassani x-pipe gave my mustang the ability to scream like a banshee throughout the entire RPM band, and the option to switch between cats and off road straight pipes is an added bonus. I personally prefer the viciousness of the off road straight pipes (which is what I'm currently running), but the cats do give it a nice deep, more traditional muscle car sound. Besides WOT pulls (to the speed limit) I love letting my car get up to about 3k on the tach in third gear and letting off the gas, the exhaust crackles, spits, and burbles. Which if you haven't experienced it, it almost feels sinful to hear something that visceral. As far as performance goes, the x-pipe definitely flows better than the stock h-pipe, which adds a couple ponies to the wheels. While you won''t really notice the slight, slight increase in horsepower you will notice the vastly improved throttle response. If combined with a good catback exhaust and maybe a tune, the demeanor of your mustang will change entirely. The unfathomable sound and improved throttle response will ensure a couple more smiles per gallon.

      Very Impressed

      Bought this based off of word of mouth and I'm very impressed. The hardest part was unbolting the bolts from the headers. PB blaster and a torch was used but had no effect due to age? Ultimately I had to go to a machine shop to let them take care of it. Once they did what they did the rest of the installation was a breeze. Paired with my S-type Borla cat backs, and I really got a great sounding V8.

      Great Sounding Mid Pipe

      This install was done on a 2003 GT with Kenne Bell Blower making 8 lbs of boost. This is the perfect sounding mid pipe. It has a deep, low, and well defined tone. It is not much louder than stock at idle, but at tip in, cruise, and full throttle you will definitely hear the difference. As far as power gains go; its hard to be certain, because my car was having some additional issues when I brought the car in to have the pipe installed, and the car tuned. At the end of the day I ended up picking up almost 60 rwhp from this mod and fixing the other issues the car was having. In total the car put down 400 rwhp and 400 rwtq (it had previously put down 340 rwhp, but was having fuel system issues a that time) Out on the street the car doesn't really feel that much faster, but that is probably due to a couple things 1) Power delivery seems a lot smoother, which usually makes it feel less strong because it isn't as violent. 2) My other Stang makes 620 rwhp, so driving a car with 200 less hp doesn't feel that impressive.

      Woke up the Neighborhood!

      After a 3 hour single man installation, it was 1130 at night when I finally got to role my vehicle out of my garage and away from my house so I didn't wake anyone up on start up. The sound between 1000rpm-2700 rpm is a deep roar, then it turns to a NASCAR like growl. Amazing, clean, crisp and beautiful modular mustang sound. Only pointer, spray every bolt down the night before installation, seized bolts were the only hiccup with my 2004 Mach 1.

      I have a 2003 Gt and I have had borla stingers with the stock midpipe for two years. I didn't think that this x pipe would make a big difference so I waited. I regret that now. The bassani catted x pipe matched with borla stingers is the perfect mustang sound. I have gotten nothing but compliments since the instal. I highly recommend this to anyone who is on the fence about buying this. It is worth the money

      The perfect midpipe

      THIS MID-PIPE IS AMAZING! I had this pipe put on with the cats installed paired to a new borla stinger catback on my 2001 bullitt and it sounds like nothing i have heard before. The best sounding mustang i have ever heard and i grant that to the bassani catted x pipe. The quality is fantastic and the finish is good too. the 5 piece design makes for an easy install, just watch your clamps for exhaust leaks. This mid-pipe sits high up to the underside of car which makes clearance good so no hitting speed bumps. With this mid-pipe you wont need the o2 extensions, or at least for me i didn't need them. Factory ones work just fine. I haven't used the cat delete pipes yet but i don't think i will because the car sounds amazing with them on and with these high flow cats, the check engine light didn't come on. In other words just get this mid-pipe and you wont be disappointed!
