Recommendations for Hi-Flow CAT?

[Techspy]

I am fed up with the rich exhaust smell at idle and have done all I know to make sure it is running correctly (replaced IACV, TPS, no air leaks etc). So, I am considering putting a CAT back on and am wondering what one is recommended.

 

I currently have a test pipe in place with a Tubi cat back system. I first want to try a Hi-Flow CAT with no muffler, but if too loud, I will put the Tubi back on with it. Fortunately I have the stock CAT and pipe untouched so I can take that to an exhaust shop with a new CAT and have it make exactly the same.

 

So, what is a tested Hi-Flow CAT? Does anyone have any videos of an S4 with a CAT only exhaust?

 

Thanks!
