  nice

  Probably one of the best X pipes you can get for your car in terms of fit and finish. Not to mention the sound. The difference in exhaust tone was like night and day coupled with my Borla Stingers. Ground clearance is not a problem unlike some other midpipes out there. This hangs flush with the undercarriage just like the catback. The modular design in being able to switch from the hi-flow cats to the offroad straight pipes is a nice plus too.

  Cats failed

  Don't like to bring in bad news , but only had them in 1 year and the MIL lamp came back for the output sensors on the Cats. I still have a good system due to the MIL eliminators and I had the system installed by the pro's so I think all was done right. Still faithful to AM.

  Bassani Catted X-Pipe

  Excellent quality. Good sound, better than my previous Bassani Catted X-Pipes that I had installed nine years ago. Install was easy. I had the cats welded in and the fit was tight to the chassis. No clearance issues. Note: Be sure and buy the gasket for (passenger side) header from Ford. Good customer service from American Muscle!

  Very Satisfied

  I just bolted this x-pipe on my car a while ago, which only took an hour with a lift, and i must say that it bolted up flawlessly to the stock manifolds. Sounds perfect with the cats bolted on, not too loud, and less raspy as opposed to the sound with the cat delete. I must recommend the sct/x3 tuner with this mod, to really wake up your car, and there is no worry about the check engine light when you get the programmer. Thanks again, AM, for the great service and great products.

  Catalyst System Codes in 1 1/2 year

  I have this on my 04 GT, and I too have the CEL for P0420 and P0430 - which indicates Bank 1 and Bank 2 catalyst system efficiency is below the acceptable threshold. They do sound great, but now I'm sweating my emissions test.

  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.

  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!

  Perfect X Pipe

  This X pipe bolted up perfectly on my 01 Cobra. I had trouble with ground clearance with a previous off road H pipe so i was curious how the catted X would fit. Even with my cobra being lowerd the x pipe has great clearance and I havent had any issues at all. It has a great finish as well an awesome sound with my maganaflow catback. The cats make it not as poppy and raspy which is nice. The kit came with everything and bolted right up. Make sure to get passenger side manifold gasket thought.

  Great Sound

  Just got this installed yesterday. Really brings out the sound in the catback. Came with instructions and all parts necessary. A+. Bassani makes great stuff and american muscle is a great source for fast shipping.

  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.

  Perfect Fit

  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.

  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.

  04 mach 1 (5-Speed)

  This is by far my favorite mod. It made me love my Steeda Cat Back a lot more. The car takes off faster and has more top end power. I am currently using it without the cats.

  Best Exhaust

  I have used almost every exhaust system out there and anytime I buy a new Mustang I always put Bassani exhaust on all my cars. Its a great sounding exhaust and worth every dollar. Magnaflow is too muffled and Flowmaster is too cheap. If you want your Mustang to sound just right, then you should buy Bassani.

  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.

  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
