I think you are comparing apples and oranges.
Dual catback exhausts will yield more power with Joe Z, ISS, and Borla yielding around 20+ peak WHP.
see this motoiq article and past Joez and ISS dynos

Axlebacks will not yield much power.
For 1000 bucks, the most cost effective options for power are New/used Borla or used JoeZ or ISS. You will still have primary cats.

Not sure about the other guys interested in this but as for me I am working with a $1000 budget and I am just trying to decide if it's better to go with a cat back Borla or an axel back ISS seeing as they will be close in price. I was under the impression that a Borla cat back could add 40hp so I wanted to see what ISS axel back gains were. I did not know that a Borla cat back exhaust put out only minimal gains that were not really noticeable

I'm not positive a cat back gets a 40 hp gain, seems to be 20 is the more accurate figure according to posts. I will wait till Jan when this axel back comes available and see what it sounds like before deciding

If you just want to go a little louder you may like the Borla axle back. I have come out of an RS5 which I put a Capristo exhaust on and also a C63 so I was just comparing it to those. There is some cabin drone but not over bearing

Thank you bullit,
Would you say it feels a lot like stock?
Can you be more clear on the drone, what exactly can I expect?
I actually started the Borla axle back thread.

I would preffered to keep my stock exhaust tips, but if the ISS turn out to be
way more awesome, I might consider it instead.

Yes its similar to stock but there is some cabin hum or drone. I am only comparing it to my previous cars which had zero drone.
I went for a drive in a car with a JoeZ system and it sounds awesome but don't think I could have it on my daily driver, after going for a drive with JoeZ the Borla axle back is very quiet in the cabin. This is just my opinion, I am sure other people will disagree. Try and go for a drive with someone that has one.
