Anybody have the CP-E N55 Catted DP?

I am looking for impressions and feedback from anyone who has the cp-e N55 (5-inch) catted DP. I am considering that as an option.

The main reason I am considering it is that while it is catted, it is a 5" pipe. Most catless pipes are 3". The flow volume of a 5" pipe is almost three times that of a 3" pipe, so my thought is that the size will offset the restriction to some degree.

Please do not hijack this thread telling us why catted DPs are a waste and recommending to go catless - that has been done to death, and anyone considering a catted DP has their well-founded reasons for looking to go that route.

I understand that you may have your reasons.. but isn't the stock DP about 5" around?

It still has to neck down to fit the cat back just like the rest of them. Don't really see a difference between any of them.
