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.

I have these pipes with Borla S-Type stingers and my car sounds amazing, very loud and intimidating. I reccomend that combination to any one who wants the best sounding car out there.

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

DerekNOrtiz Year: 2003 Model: 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.

Can i install this with the stock manifold (99 GT) can i put this on my stock manifold with out any problems.

MrTea Year: 1999 Model: GT

  • Absolutely! This O/R X-pipe would bolt right up to your stock manifolds to replace your restrictive factory piping!

    Got this x pipe for my 01 gt with borla stingers and let me tell you it is LOUD. The stingers alone were not loud enough for me and this pipe will satisfy just disire for volume. It does have a raspy sound at about 2100 rpms and up but it also makes the 4.6 sound like a screaming beast. Be weary of installing the pipe on the exhaust manifold because if you hit the starter solenoid with a metal tool it will shock you of you don't disconnect the battery. When I idle in traffic the smell is pretty strong without the cats. Turns heads wherever I go, all the camaro's sound tame in comparison.

    Awesome Sound!!!

    I ordered this bassani o/r x pipe about 6 weeks ago and let me tell you, since installing this product, all I've gotten is compliments on how good my gt sounds. I have a 03 gt with a k&n cold air intake, this bassani o/r x pipe, and a magnaflow catback and my car sounds great. The next step is to get me a different catback. Even though the magnaflows sound good I'm thinking of getting a lm1 or borla stingers to go with my x pipe. This product is great and i would recommend this product to anyone with a mustang.

    Great Product

    Shipping was fast as allways with, went on nice and smooth on my 1999 SVT Cobra, Sounds great, nice and loud just like a O/R X-pipe should! I have had it on now for 2 weeks and no problems so far. My car feels like it pulls so much smoother now, its great. Just need to buy a tuner now for my Engine Light lol.

    Worth it

    Great cross over pipe. Little bit more raspy then the H-Pipe, but also more powerful than the H-Pipe.

    SO LOUD!!

    So this is the first time I have ever written a review for anything I put in my stang and the reason I am is because it's such a great product. The fit and install was perfect and I am not a mechanic by any means. Also the sound you get from this X pipe is unbelievable, borla stingers are loud but this is extremely loud and it'll never get old. No more creeping around anymore because everyone will hear you coming. First time driving it out on the streets and I could read people's lips as they were complementing my car. So yes I highly recommend this product.

    Best Brand X pipe there is.

    I bought the Bassani off road X and paired it up with the Borla Stinger catback. The car is so much louder and has the best sound there is for my 03 GT. The five piece design helped installation easier and quality is flawless.
