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.

Fitment. This Catted X-pipe fits both 2005-2010 Manual and Automatic transmission GT Mustangs. The 2005-2010 Automatic GT mustangs require the use of O2 extenders, see drop down option above.

5 Top Rated Questions

Is it California legal?

  • The Bassani Catted X-pipe is not tested or approved by the California Air Resource Board (CARB) meaning this is not legal for use upon highway in the state of California.

Does this make you fat have a check engine light?

  • The Bassani Catted X-pipe would not cause a check engine light since it still retains the cats.

Helpful (0)

If I install this with the stock 07 gt premium mufflers ( not sure if different from base model gt) will I throw a engine code with the cat delete pipes installed? If so what are ways to get rid of the light. Or can I just change them out with the cats and be fine for the inspection?

  • If the cat-delete pipes are installed, the vehicle will produce a CEL. We would highly recommend a custom tune so the cat delete can be calibrated for in the tune. We would recommend the Bama X4/SF4 Power Flash Tuner w/ 2 Custom Tunes, item 101200G05 for a customer calibration.

Does anyone know the exact specs, length and in/out diameter, for the cat piece?

  • The Bassani Catted X-pipe will include two cat pipes and two cat eliminator pipes. These will have a 2.5" ID inlet and a 2.5" OD outlet for both the cats and cat eliminator pipes. Unfortunately at this time, Bassani does not publish the exact length of these sections of piping, since both are included.

Should I get Catbacks or Axelback Borla Stingers with this xpipe? Would Borla Stinger Catbacks or Axelbacks sound better/produce better air flow with this x pipe?

  • either one would work, but i would suggest a cat-back just to get a slight bit more flow and cleaner sound.

    Issue with cat

    Will be happy with this x pipe when it sounds like it's supposed to. One of the hi Flo cats I received was defective which makes it sound like junk. I know these sort of things can happen, but I know American muscle will make this right for me. The 02 sensor extensions were not needed.

    Definitely worth it.

    This product is really nice. the location change of the catts makes it a bit lower, but i haven't scrapped anything yet. The sound is amazing and its easy to install. The other nice thing is when it comes time to replace my catts i wont have to cut or weld anything. Thank you Bassani for a nice product that directly fits. -2005 Mustang GT, Steeda shorty headers, Bassani catted x-pipe, and Magnaflow catt back.

    Amazing product but really frustrating

    I was so happy when I got this part. I figured it would pair well with my Bassani Axle Backs. The sound is great, its loud without being obnoxious and Im sure it will be even better when I get my newest tune loaded. I was going to run without catless but then changed my mind. Originally I had planned to do the install with my uncle but after we took a look at it and also found out that my nose was too low to get up the ramps we had, we took it to the exhaust shop he uses. It was at least a 2 hour install but thankfully the guy knows my uncle so he cut us a break and it only cost $100 Now for the bad. It was a pain to install. The pipes didnt want to fit together and there was some bending and smacking and stuff that had to occur to get everything to fit. The biggest problem is that this thing sits low...and I mean really low. I had just raised my car up a bit to fix my problem with hitting my cats on speedbumps, and now my overaxle pipes are seriously low, because of how this all fits together. *sigh* this is sooo frustrated

    Paired this x-pipe w/ Borla!

    I picked the Bassani catted X-Pipe up along, with my Borla Axelbacks. Fit, and finish could have not been any better, and that with the sound, is phenominal!! Definitely helps eliminate the raspiness, while maintaining a very aggressive tone. All in all I highly reccomend the Bassani catted x-pipe, for anyone looking to attain a rich, muscular sound!

    Awesome x-pipe !!

    These x-pipes are very well built, exactly what they claim to be. It took me about 3 hours to put them on, 2 of those hours were spent taking the very restrictive stock h-pipe. They bolted right up no modifications need , just gotta find a spot to hang the excessive o2 sensor extension. Wouldn't recommend pairing these with flowmaster 40s sounded like a tin can, put on some new borla stingers sounds amazing. Back to the x pipe I love the fact that the cats bolt on and off makes it easy to run no cats and then bolt them on for inspection. The high flow cats are great I have those on right now. Thanks American Muscle for another great product!!

    Bassani Catted X

    Beautiful piece of metal work. I've had mine for a year and the metals have broken in nicely and the sound is not overbearing or overly raspy when paired with Bassani chambered BX axlebacks. Drone is almost completely gone! I noticed a small loss of low-end but mid/high rpm power feels a little better. However I wouldn't not purchase it again, or anything from Bassani for that matter. Installation was a nightmare, I may be a perfectionist but, nothing lined up when swapping pipes; not even with torches or lifts. For the second time with Bassani products I was forced to settle for a "good enough" result. Also be wary of ride height, because the position of cats is dramatically lower than stock. My lowered '05 GT scrapes the Bassani cats on everything. In summary: for the claims made, it did not meet even my lowest expectations.

    First Rate Product

    Love the sound with the JBA mufflers I used though I realize that is subjective. What is not an opinion is the extremely high quality of the product and the ease with which it mounts. It is truly a bolt on. Bassani goes the extra step with band style clamps as well. Highly recommended.
