Any sound clips?

Unfortunately I do not anymore.

To be honest if you live in an apartment complex, the cold start will not make you any friends. Other than that the exhaust tone has lots of deep volume driving normally. Wide open throttle and it gets rowdy.

My current exhaust set-up hasn't seen the neighbors complain yet!
Sure tempting, don't think my wife has that much cheddar in the secret compartment in her purse though!

Got any sound clips of this? Have you paired it with an x or h pipe with dumps similar to what OP did?

No sir - what ya see is what ya get! I rarely drive it on the street except to datalog it. It actually isn't much louder than the active exhaust it came with but when you hit the gas it is LOUD!!!
I'll go start it up & post a clip in a few.

The initial start up where it revs to 1100 or so it's pretty loud, once it gets below say 1000-900 it's actually fairly quiet.

The catalytic converter quiets the car down more than you would think. Plus, the long tube headers over the stock headers ad noise and volume, ad that to everything being true 3” all the way out back. The bullet mufflers are more for show than noise reduction. The series I was racing in required you to have some type of muffler.

End of the day I want potential buyer to be aware this is not close to stock sounding exhaust and not have them have buyers remorse once received and installed.

I am wiling to negotiate price as long as offers are reasonable. Shipping on the other hand will probably be around $300ish due to size and weight.

Old pic for attention lol

Here is an IG link to the gentleman that did the fabrication and welding. If you click on the 5.0 Mustang story line, last post has a short clip of me backing the car out of his shop. Hopefully that helps? Mostly just idle and slow moving.

Guessin' you were running a "true street" class that required mufflers then? That is the only reason your set-up piqued my interest initially - there are a few "true street" events I'd like to run but sure as hell don't want to put that heavy factory exhaust system back on in order to run it. Looks like your set-up would be perfect for it.
My only hesitation is the fact our racing season is so short here - we've only a few races left this month, August and September, assuming the weather starts cooperating. I will give it some serious thought before making an offer.
Thank you for the information, I appreciate it!

Some seriously nice work, guy is an artist with metal fab!
I removed my exhaust system solely for the weight reduction - sounds pretty good at WOT!!!

End of month bump, still available!

If the Mustang wasn't my daily (and I didn't go to work at 7am some days, get home at 2am others), I'd be seriously interested in this thing. Dude who made it crushed it. And it sounds wild in his ig clips.

Free bump for ya!
