Description
Improved Horsepower. The Bassani Catted X-Pipe uses free-flowing mandrel-bent tubing and high-flow catalytic converters with their unique Power “X" Crossover pipe design that scavenges exhaust gasses to provide a significant horsepower increase over the stock restrictive factory catted pipe. Modular Design. Bassani uses an exclusive five-piece "modular" design that comes with catalytic converters and off road delete tubes making it possible to switch between the catalytic converters and the off road delete tubes on race vehicles.

Quality Construction. This Catted X-pipe from Bassani is constructed entirely from mandrel-bent stainless steel for a durable long life. The catalytic converters use Metallic Substrate for excellent performance and use all the factory emissions connections.

Lifetime Warranty. The Bassani Catted X-pipe is precision-engineered from resilient stainless steel for long lasting durability and is backed by Bassani's Lifetime Warranty.

Application. This Catted X-pipe fits 1999-2004 Manual GT, 2001 Bullitt, 2003-2004 Mach 1 manual and 1999-2001 manual SVT Cobra Mustangs. The 2004 manual GT mustang requires the use of O2 extenders, see drop down option above.

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

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?

  • Yes, this midpipe will fit the 2003 Mach 1 (manual transmission). 99-04 GT's, Mach 1's, Cobras all share the same midpipe. The only exception would be that for the 04 GT, Mach 1 and Cobra, O2 extensions will need to be purchased to go with the midpipe.

  • This X-pipe is designed and the proper length to bolt up to stock manifolds or shorty length headers. Unfortunately, it's not compatible with long tube headers. For the BBK LTH, you should pair that with a matching BBK Shorty Mid-pipe for proper fitment.

  • Yes, i have it on my 02 Roush stage 2 going into flowmasters, soundsgood but not excessively loud. If you want LOUD go with the O/R X pipe. I had a catless x into magnaflows on my 98 gt and it sounded mean.

    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.

    Very Satisfied

    January 10, 2011

    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

    December 16, 2010

    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.

    Bassani Catted X-Pipe

    May 10, 2011

    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!

    Cats failed

    March 04, 2010

    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.

    Woke up the Neighborhood!

    June 01, 2013

    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.

    Perfect X Pipe

    September 29, 2011

    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.

    The perfect midpipe

    August 11, 2012

    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!
