I did....but a "noticeable difference" is subjective which is what makes this so difficult. I would go Tubi Style straigt pipe (valved) with a Cargraphic if you want more and deeper sounds and iPE if you want the ability for improved volumee with the ability to significantly tone it down with valves set to normal (i.e. big sound delta between the two. You could also go to a cars and coffee to walk around and find somebody with a cat back center to have a listen. In the end I look at it this way: by virtue of looking at potential sound improvement solutions we're already accepting that stock is not enough so doing nothing is was not a choice for me. If you put on the cat back and are underwhelemed, then you can go highflow downpipe.

Let me kniw what you decide to go with and if you like it.

Hi,

I hope you don't mind me messaging you directly. I've got a 992GTS with cargraphic controller installed. It's made a difference at slow speeds/lower revs but I'm still considering a cat back, like the JCR. Did you ever get to the bottom if it makes a noticable difference over the PSE? It's a lot of cash and could be a little underwhelming without sports cats.Seems hard to get a straight answer!

Cheers,

Steve
