Ask a Question

Since this x pipe does not delete the cats, what would I have to do along with this system to delete the cats?


  • Since this system is bolted onto the exhaust right behind the cats, to delete them you would either need to cut them out and have an exhaust shop custom modify piping to take its place, or purchase the catback with an off-road X-pipe that would automatically delete the catalytic converters.

Is this compatable with kooks long tube headers or would I need cat deletes in between?


  • This exhaust kit is designed to work with the stock manifolds or aftermarket shorty headers. This kit comes with the needed down pipes and reuses the stock catalytic converters. You may need to do some modifications in order to make this exhaust system work with long tube headers. Unfortunately, they may not be a direct bolt on.

Some say there is drone, while others say there isn't. If drone does exist, is it at least bearable at cruising and highway speeds?


  • It would be difficult to say how it sounds as sound can be subjective. To some enthusiasts it is not to bad, and to others, the sound is unbearable. I would recommend watching a few in-cabin sound clips to see if this is something that appears to you. The Bassani Cat-Back and X-Pipe Combo consists of glass-pack style mufflers, so the sound will be aggressive.


Helpful (0)

Does anyone know if this Bassani exhaust will still clear the floor pan with a 2" drop in the suspension?


  • It will fit the same as the body itself doesn't change when lowering springs are installed. What it does do is lower your car closer to the ground. If the Bassani exhaust hangs lower you could have issues going into driveways, etc. Just be sure when you install it everything is tight and hung properly.

Resonators come with? The pictures show resonators after the x pipe, but the description doesn't mention them. Does this kit come with resonators and mufflers?


  • Yes they do come with the resonators. I installed the exhuast myself. Took right around 4-5 hours with me and another person.

    this exhaust sounds amazing

    This exhaust was a great purchase, and easy to install. It took a little more than 4 hours hours to install, and that was in my garage with the help of jackstands and a floor jack. The hardest part of the install was getting the factory pipe over the axle. I ended up cutting it with a sawzall. The exhaust is extremely open and has a great tone from idle to 7000rpm shifts. I recommend this system to everyone. Good price, great fit, and great sound.

    quiet cruiser, loud racer

    My car has an E-force supercharger and I would expect the sound of this exhaust to be different than on a normally aspirated car. For me, the sound is tame when cruising, but really rips when pushed hard. It can also be a little loud when on the warm-up cycle. The quality is great, its made in the U S, and the shop that installed it said there were no issues.

    Love the exhaust. Sounds nice and deep and isn't to loud and little to no drone even with my bbk cat deletes. At least till you give it wot then she screams and gets all the attention. Great product and great parts biggest issue with install was removing the stock parts.

    SUPER DEEP tone.

    Bought my 14 GT with this catback already installed. Car sounds awesome, amazingly deep tone. Sounds so good. Not super loud around town, but opens up pretty good when you put your foot down. It does drone a bit under 2200 rpm, but nothing the radio can't cover up with ease. I'd personally like it to be a bit louder but don't mistake that for it being quiet. I've heard corsa setups and they do sound great and are loud but the deep tone can't be beat in my opinion.

    Very well made, with a great sound

    My mustang had a Magnaflow cat-back system when I purchased it. After too much research, I decided to put on a Bassani cat-back with a Bassani x-pipe. The finish, weld and quality of the product was on par if not superior to other high end systems. The exhaust sounds great and is something I can feel a difference in when I drive. Quiet at low rpm's and angry when you open it up. My only negatives are that I wish it was a little louder and the exhaust note is more raspy than deep (probably a little to do with the x-pipe). I would definitely purchase again.

    You won't be disappointed. -Black GT/CS

    To start, I think it sounds amazing! I was going for the 'roar' sound and after viewing videos online, lets just say the videos don't do it justice. I love how it sounds just cruising, It's much louder, so obviously you've got cabin noise but you'd be dumb not to understand louder exhaust = louder cabin noise. The exhaust itself looks great, and the original pipes were getting a little aged look on them, and this made it sound so much better. My first impressions, on startup I literally got goosebumps it sounded so nice! It does have a noise cap at higher rpm's when revving, but when driving, it sounds amazing. I may put some headers on it next, but even with stock it sounds great! I would definitely recommend this if you're a car guy and you're looking for the roar like I was. I'll even have a proper video up on my channel of startup and revs, hopefully it can be put up on here! :) Small note, this exhaust does hang a little lower than stock. I'm not complaining, but it's worth noting. First car I'm changing the exhaust on, and I don't have a price for putting it on as my brother is a mechanic, and was going to do it free... but I still gave him 40$. Details on install below review. The install wasn't easy as without a lift we weren't able to get enough clearance to remove the stock exhaust, honestly that was the hardest part. The second hardest part was that the X pipe to cats was not wide enough to fit, and took some force (not a lot) to get properly into place. Once that was on, we used a ratchet strap and the exhaust fit like a gloves after that. Then we tightened it up and it was good to go! Install took around 2.5-3 hours. though that's probably because my brother is a mechanic and does this already. Overall, i'm still a very happy customer!

    Very loud, in a great kinda way!

    Received from UPS on Wednesday, had it put on at a shop on Friday, it took about 3 hours for the muffler shop guy to install. They said everything fit well but it took a little time getting everything all lined up. It looks great, but it sounds even better! Got two complements on the sound the first afternoon, a UPS driver shadowed me for two blocks just to listen to the sound, he said, "Thunder man, sounds like thunder". I love the sound, but don't recommend it to the mild at heart, you have to be a 'car guy' to appreciate this exhaust.

    Worth it!

    The only reason its not a 5 rating is the fact that I will have to make a bracket to shift a muffler over they are off center right now. Other than that, The noise is amazing. I ran my 5.0 trough a tunnel today and 0.0 WORTH EVERY PENNY!!

    From the start to finish this exhaust was fairly easy to install. It was mainly plug and play with a little finesse required for fitment. The performance gain is right around 35-40 HP/ 20-25 TQ. This is the best sounding exhaust I have ever heard on any 8 cylinder vehicle. If you are into a quieter exhaust this is not for you. At WOT words cannot describe the exhaust note that sounds off. In my opinion this is the best system you can put on any mustang. The price is moderate-high but is worth every single dime. I have 0 regrets with purchasing this exhuast.

    Make a statement

    Honestly, AM should provide sound clips of this exhaust. Probably not the choice exhaust for everyone, because it starts to get loud really fast over 2k rpm. No question, you will get noticed with this. But if you don't mind the loudness, the tone is awesome. Have to say, I wish it was maybe a tad bit more tame, and there is drone, no question about that. But stand outside this thing while someone steps on the gas for you, and it will give you goosebumps.
