Has anyone ever tried DP+MP with stock catback?
 

As in the Subject, has any of you ever tried this?
Considering italian laws, cops will not like a new catback, even if quiet, so I was thinking of keeping it, or at least have it opened and the inner things replaced with a straight (silenced) pipe (but in this case i will need a resonated midpipe to keep sound low

Just buy a dual tipped cat back.....
Get it painted/coated black, and they will never know.

Tried it...its still loud, even with a resonated mp.
