That is GORGEOUS! What did it sell for?

I wish I had the space and skill to do that!

Haha, it sold for much less than I had in it (as with every single previous build) except this 68 I sold last summer

I was interested in trying it but if I didn't like it, putting it back to stock would have been a pain so sticking with my current set up.
You could also get just an aftermarket midpipe, GThaus or Apexi, and swap that in. It wouldn't require any cutting.

I will try and get some audio this weekend. I would say just the axle back sounds good. I think for me I don’t feel like removing the resonator and secondary cats would be worth it at this point and may be too loud. This coming from someone or sold their 2016 mustang gt with full exhaust.

You'll probably end up getting the midpipe too, they all do and then headers!! lol

FYI to anyone reading this.
GTHAUS stainless midpipe ETA 4-6 weeks, titanium in stock.
Apexi non resonated and resonated midpipes ETA June.

GTHAUS axle backs are good in stock in all variations
Apexi axle backs are arriving in May.

Which part is the bigger restriction, the stock midpipes or the stock axlebacks?

from what I’ve seen, stock axle back!

but secondary cats are restrictive too, so...

I thought that might be the case given the flattened section. Just getting the GTHaus axleback is very tempting.
