I had mine removed and had the software update. It is pretty big difference for me... at least 30% louder.

Say you perform a secondary cat delete and the sound or 'loudness' isn't enough, where do you go from there?
Assuming that a cat-back or muffler is probably the most expensive option, is there something else more cost effective?

Anyone get this done around West Chester PA?
Took my car to a fairly decent shop today and once they had it on the lift they called to say they’d have to drop the trans and remove the downpipes to do the job. Ridiculous.

It IS pretty tight. But I insisted that others have done it without removing the DPs. The guy reluctantly did it, and did it well.
Having said that, I wouldn't push someone who's not comfortable doing it to do it. Just go to a high end muffler shop. It's not rocket science...

Thanks.
I saw mention earlier in the thread thread of one shop welding a flange on via the inside, which would understandably make it a bunch easier than squeezing in around the top where it’s tight, on the outside. However, from most of the pics, it seems like the weld bead clearly was done from the outside, not the inside, so I’m thinking that “inside flange” method was the exception.
