Was pretty easy to install after getting the factory pipe out. Sounds very good, taking me some time to get used to the raspyness @2k or slightly higher rpms, but I am hopeful that will be taken care of ...

Will this x-pipe fit my 2001 mustang GT 5-speed with stock headers. Will it also fit up to SLP LOUDMOUTH 1'S CAT BACK SYSTEM?


  • This mid pipe will be able to fit up to your stock headers as the flanges were designed to accept the stock header flanges. This will also fit to the SLP Loudmouth's as the pipe size is the same.

Have an 02 GT and was wondering if a setup with the Slp longtube headers with bassani O/R x-pipe and Borla Atak exhaust would work. Reason for asking is that when I pull up Long tube compatible x-pipes the bassani O/R x-pipe isn't on there, it's on stock length compatible category.


  • The Borla ATAK Cat-Back Exhaust (99-04 GT, Mach 1), item # 29030, ( is a direct bolt on to the factory Mid-Pipe. You may need to do some modifications in order for this Cat-Back to bolt to the Bassani X-Pipe. Also, this X-Pipe is designed for shorty headers. The SLP Ceramic Long Tube Headers (96-04 GT), item # 23000, ( will not be a direct bolt on with the X-Pipe. You will need to have some custom work done in order to make these parts fit together. We suggest having everything professionally installed to ensure you have no exhaust leaks and proper fitment.

Will this fit on a 2003 Mach 1 (stock headers)? I see some comments that say it does, but I wanted to be sure.


  • As long as your Mach 1 is a manual the Bassani Off-Road X-pipe - Manual (99-04 GT; 99-01 Cobra) will fit just fine.


    Helpful (0)

Will this fit an 03/04 Cobra?


  • The Bassani Off-Road X-pipe - Manual (99-04 GT; 99-01 Cobra) will not fit a 03/04 Cobra as the 99-01 Cobra X-Pipe is a different length than the 03/04 Cobra. This would need customer modification to fit into the exhaust setup for a 03/04 Cobra.


    Helpful (0)

Will this fit an 04 Cobra? Description just says it will fit Cobras up to 2001.


  • The Bassani Off-Road X-pipe - Manual (99-04 GT; 99-01 Cobra) will not be able to fit the 2003-2004 Cobra's as they have a different length to their X-Pipes which will not allow the Bassani Off-Road X-pipe to fit their exhaust setup without modification.

Will this x pipe bolt on to my stock s281 SC borla system?


  • The Bassani Off-Road X-pipe - Manual (99-04 GT; 99-01 Cobra) should have no problem bolting up to your system as long as the pipes under your Mustang are routed the same as the factory pipes on a GT model.

    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!!!

    Good Pipes

    A little bit raspy, but considering the power and tone I get, I can deal with the raspy sound. On my 03\' Mach 1 they sound and perform great!

    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.

    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.

    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.

    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.

    When sound and performance collide!!

    Amazing Product!! The sound is unrivaled and the performance gain is everything you want it to be. Check out some "How to" videos/forum discussions because it can get tricky when removing the passenger side stock h-pipe. And get a pair of good exhaust clamps because they're not included. Buy it. Put it on. And go SS hunting!!

    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

    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.
