I have the 3” Solo Performance cat back with FP Stage 2 tune and it has all the noise you are looking for and it’s comfortable to cruise in.@

If you can please post a video
Next time I go out (it’s raining pretty good right now) I will record something with windows up and down. Windows down might suck because of the wind and I am using a phone.

My FRPP quad exhaust is enough for anyone. Can't beat it.

I can't find one for the Mach 1 especially 1 that allows me to keep my active exhaust unfortunately

GT350 here, I have the resonator delete and in sport mode for the exhaust I get plenty of crackles and pops on decel.

My Bullitt has plenty of "crackle & pop" with a Steeda X pipe and tune...and I love it in Track.
The Bullitt has a burble tune that I think is unique to it, and no other Mustang. Pretty sure I've seen screenshots of it tuning discussions.
I have the instructions of how to set up the Bullitt burbles for the GT, I can post them tomorrow if it’s useful to this thread ?

That would be great.
Here you go :

"There is an additional drive mode feature that can be enabled in the tune, and it’s the Bullitt burbles.

If enabled they will be activated in all modes except Normal.

Instructions for HP tuners :

First change these settings under "engine>fuel>Cutoff, DFCO" to the values shown below :

Then populate the Target TR (Sport) table as shown :

Then populate the Duration table as shown :

1707381903970.png


This is copied directly from the Bullitt mustang so I have confidence in its safety for long term use. I've been running it for a while now. You can mess with the Duration and Target TR (...) tables to make it happen more aggressively or for longer but I found that the stock values are very good not obnoxious and easy to control. I think if you copy the Target TR (Sport) to Target TR (Normal) then it will burble in normal mode too but I haven't tried it so it may work or it may not. I also prefer having a mode without burbles.

Also I do not know if this works on pre-2018 models, it is my understanding that this logic was designed specifically for the Bullitt mustang so it may not be present on operating systems prior to that car's introduction.

Here is the result with the Active Exhaust wide open :



Have fun! You can also ask your tuner to enable this for you as well"

Note that I can't take credit for that, neither can I vouch for its accuracy or effectiveness - I just stored the info for future, and luckily I also saved the link to where it came from :like:

The Steeda H pipe/resinator delete gave me plenty of crackles and pops on downshifts. I hated it and took it off lol. It also rendered the AE modes almost useless.

That's definitely not true. There's one model of the system, and it just replaces the mid pipe with an X, plus the added side exit exhaust. Perhaps you're thinking I'm referring to the rear exit exhaust.

Look at my post history for pics and video if you want.

That sounds amazing, do you have any videos outside the car?

If you have Active Exhaust, delete the resonator, install an H or X-pipe and drive around in Track Mode. That's literally all you have to do. You don't need a tune or any fancy exhaust set up. You will hear LOTS of burbles on deceleration.

I've uploaded the only two that I have. I guess I need to get better about it and get some more seeing that I think I'm the only one with the system installed.
