How restrictive are the stock resonators? Is it worth while to remove them for more power?

I am thinking about installing two dynomax super turbo mufflers and I was also thinking about getting a resonating tip, is it worth it if I leave the stock resonators on?

 

I did that before getting my AEM CAI. I think it is worth it. It sounds better as well as a bit of added power from my butt dyno. It also saves some weight as well

 

HMMM!! haha.....how much more sound does it give? cause i remember taking it out on my friend's 00 Accord V6...man..it was still so quiet! then again..he's a chicken butt when it comes to VTEC Range and Redline..
