Improved Horsepower. The Bassani Off-Road X-Pipe uses free-flowing mandrel-bent tubing and 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 making it easy to add catalytic converters to their X pipe in the future if the need should arise.

Quality Construction. This Off-Road X-pipe from Bassani is constructed entirely from mandrel-bent stainless steel for a durable long life.

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

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

      Why is "Manual" next to the kinda of pipe it is. I just got my 2003 Mustang GT and want to put a good set of pipes on it, im a little confused when it says manual, does it have to have a manual transmission, i have an automatic i was wondering if i could still put these on my GT

      • Correct. When it lists manual, that is referring to the transmission type. Unfortunately, this particular mid-pipe won't fit properly on your automatic.

      What is the difference between this and the more common Pypes off-road x pipe? Why is this so much more expensive?

      • A number of factors go into the price points on items such as the materials used, cost of construction, and marketing. Specifically this will feature Bassani's unique Power “X" Crossover pipe design that scavenges exhaust gasses to provide significant HP increases.

      Would this fit my 04 gt with bbk long tube headers

      • This mid-pipe would only work with the stock or shorty headers.

      Would this x pipe fit with the Bassani mid length headers on a 99 Cobra?

      • This mid-pipe would only work with the stock or shorty headers. For mid-length headers, you would need a mid-length mid-pipe for this.

      Will this bassani x pipes fit my 5 speed 03 mustang gt??? The only upgrade I've had done to my exhaust system is a pair of Supper 44 Flowmaster mufflers.

      • Yes will be compatible with your Mustang! The Bassani Off-Road X-Pipe fits 1999-2004 Manual GTs.

          Blaah blahh blaah

          Every since I wanted a Mustang, I already knew I wanted a Bassani X Pipe. Sounds soooo goooood paired with magnaflow magnapack mufflers. It can be loud, it can be quiet, all depends on what mufflers you're running. Definitely worth it.

          1999 Cobra Bassani O/R X-pipe

          Excellent sound. Fits perfect to OEM exhaust fittings. Be sure to order SR Performance MIL eliminatos for your O2 sensors (eliminates engine light code and also acts as an extender since your OEM O2 sensors won't reach). I also had Borla stinger 40842S (no notch) mufflers welded in place of the OEM mufflers and WOW!!!

          Quality product, no disappointments!

          Love this x-pipe, especially at the price. MIL eliminators seem like a fine alternative, as mine have worked so far. I'd say the hardest part of this install would be making sure the passenger side flange meets up with the manifold properly. Unlike the original exhaust, the x-pipe doesn't have any piping that comes through to line up with the manifold. Therefore, you have to do all the guess work. My recommendation would be to buy a new gasket just in case you have any issues. Or if you didn't have any issues save it for a later date as I did! Other than that, everything else is like putting Legos together, just slides together.

          Looks good

          The passenger side vibrates against my transmission mount bolt. Not to happy about it after taking three hours to uninstall the old pipe and put in the new. Also when I received xpipe it only came with two pipe clamps that were way to big. AM sent me 4 correct clamps right away.

          Bassani X pipe

          Sounds great. The hard part was getting the stock exhaust off. The borla stingers and the x pipe work well together. Noticeable gain in power.

          Best fitting o/r x-pipe

          I've had several mustangs , and installed several ( less expensive)x-pipes . This is by far the best fitting one I have bought . I guess you really do get what you pay for .

          Best O/R X out there

          Have this x pipe paired with the Borla ATAK on my 99 cobra. The ATAK added a nice note with stock catted pipe, but my plan was to always replace that thing. A friend got an O/R h pipe and it had a decent tone but didnt have that in your face sound. I figured with all the reviews of this i would give it a shot. well worth the money. Everyone knows when im coming, and often i get the police called on me even though i am obeying traffic laws and noise codes. the sound is very raw in the pairing i have and would recommend for anyone wanting the meanest sounding mustang out there

          Great Sound!

          Installed this X pipe and tested it with stock exhaust, fantastic quality. Truly brought the car to life with the sound. Highly suggest this product. Takes about an hour to an hour ½ for full removal of old x pipe and installation of new one.

          Life Changer!!

          I had the BBK off road x pipe on my car for a long time. It bottomed out and scraped on everything and I thought it sounded good. I installed the basani x pipe and it sounds incredible!! Takes the raspy cheap sound away that bbk offers and the ground clearance is also perfect!! Makes driving my car way better!!!
