How much drone are we talking? From what people have said there isn't any when replacing the secondary cats with an AFE or Supersprint midpipe. I've already got the PE muffler with resonator delete installed. Looking to remove the secondary cats next.
Like I've said the bottle style resonator removes any drone that would be noticeable. I'm able to listen to music and have normal volume conversations in my car with this set up. Now when I put the windows down and floor it, lots of good exhaust notes comes out the tailpipe and it's very enjoyable.

Mid-pipes delete the secondary cats.

I really like it and would recommend it! Maybe a muffler delete next?
so you still have the secondary cat in place? I'm thinking doing the same setup

Like the above poster said, the AFE mid-pipes delete the secondary cats - so, no. If someone is using these pipes the secondaries are gone. O2 sensors are upstream of the secondaries so it doesn't set a check engine light.
