I have a 2017 5.0 with only a ford racing x-pipe/res del. and roush axlebacks. I am debating adding a set of long tubes (obviously accessory parts/tune), but not sure what the best addition would be. I'm wondering about fitment, and whether there is a setup I can throw on without needing a new a midpipe adapter; if there's no way to avoid a new midpipe/adapter, any suggestions on the best sounding or most "bang for buck" system? (staying catted)

In addition, this is my daily and I'm concerned about drone with added headers. Anyone live/daily a similar setup?

Just curious, is your mustang pretty loud already though with your set up, res delete, x pipe and roush axle backs?

Long tube headers usually come with their midpipe. So, your best bet is to have a customize one from a muffler shop. In other words, you will not be able to use the current midpipe you have.
As a for sound, it varies from one individual to other. I have long tube headers with an off road x pipe and it makes the car sounds like a nascar car and I enjoy it to the fullest, but I'm sure for some other mustang owners, it may be too loud or ect. Some are going to tell you go with this brand or that other brand, but at the end, it's about your decision to know exactly what you want in terms of drone, loudness and else.

My car now is decently loud. But its by no means unbearable. Here's a clip link of it, and there are many more that do the setup justice.

That's what I figured, makes sense. Drone typically doesn't bother me, but passengers get a headache. Then again, the car isn't for them lol. Looks like ill be listening to more sound clips until I decide on a system that fits my taste. I'm a sucker for the raspy high pitch on these modular motors and I cant imagine it being too loud (for me anyway, sorry neighbors) Thanks for the input.

If you like the raspy sound then you should go for an X pipe and it's certainly going to give you the sound you want.

I have the brand Pypes (long tube, mid and axle back) and so far, in terms of sounds, I can't complain. It's extremely loud and people can hear me coming even from half-mile away. Moreover, on WOT, it goes super loud and I f.... like it!

I have Kooks long tubes, cats (to keep it legal), H-pipe (no rasp) and 2010 Ford/Shelby axlebacks. The car has a unique sound which is different from others that I've heard.
BTW - 2013 GT 5.0 Tuned

I like the setups I'm seeing. If anyone has sound clips, feel free to post them. However, I do prefer catted, since I will definitely stay catted.

I can not overstate this small piece of advice: Make absolutely sure you know your local emissions requirements before you even think about going with long tube headers.

In Houston, this is a serious PITA. I had a 2010 GT with nothing but long tubes, mufflers, and high flow cats. It would not pass emissions. I worked with BAMA on that stupid tune for over two months. It never did get through inspection and I wound up selling it.

Fast forward to today: I have a 2004 Mustang GT with long tubes, mufflers, and high flow cats in my shop right now. We can not get it punched through inspection. When it came in, it had a tune on it to turn off the rear 02 sensors to prevent the check engine light from coming on due to extra flow. Well, in Texas, that doesn't fly. With those turned off, the EVAP system never sets, nor does the catalyst. You can only have one system not set to even start inspection here, as ours works by plugging the car into an inspection station that is tied into the DMV. The tech doing inspection has absolutely no say...the computer reads what it reads and gives you the result.

We tried slapping MIL Eliminators onto the car. Now the evap is set, but the catalyst and 02 sensors won't so we are STILL stuck. TWO WEEKS into trying to shove this car through inspection. Now, this particular car has a few extra items on it too (cams, etc.) but we run into this all the time.

Just a piece of advice, nothing more. If you have no emissions, then you have no worries. But DO NOT assume high flow cats will keep you legal. They burn less than the factory cats and will not cook off enough pollution to get the car passed. Not in our county anyway, and we don't use a sniffer.

You're so spot on with this, I was actually thinking about this earlier. Being in Central/South Florida, there's no worry (as there's no testing). However, I may be moving a few states North which could put me at risk if I don't check out all my corners. I'm glad you emphasized that point, I will definitely do massive research across all possible locations prior to making a permanent decision.

I'm glad to help. I wish someone had spoken up when I was considering doing long tubes back then.

It's not that it's not possible to pass: We've since gotten that '04 GT out of our shop. It finally set the catalyst and we got it through. But it's the time, the pain in the neck, etc. that makes it not worth it.

I'm glad to see you are looking into the laws where you will be moving. That is extremely smart. I'm all for modding and LOVE the sound of a nice set of headers, but you just have to make sure you aren't setting yourself up for headaches down the road. :smartassony.jpg
