Resonator and muffler delete = ear bleeding drone!
Magnaflow tru-x fits perfectly in resonator location (see pic) but does very little to eliminate drone.
"J" pipes installed in the location of deleted mufflers eliminates all drone and car has incredible exhaust note. One of the other members here pointed me in the right direction but I can't recall who it was now. If you search for "J pipe" you should be able to get some great info on the subject.

Here's what I have found from my personal experience:

How do these cars sound if basically stock exhaust besides headers, and second cat delete? I don't want anything too loud. Only exhaust upgrade I have is headers. Was thinking about removing secondary cats and calling it a day.

Has anyone tried second resonator delete, with Borla replacing the stock mufflers?

That certainly would be one option and some of the guys here have done exactly that and been happy with the results. I was looking for a little more aggressive exhaust tone so I removed the 2nd cats, resonator and stock mufflers and then started adding components back. The x pipe basically does nothing to reduce drone or overall noise level and we knew from the beginning we wanted to try the Magnaflow in place of the resonator. After installing those two items the drone was still deafening somewhere between 1800 and 2300 rpm so I put some 12" bullets toward the rear of the car. The bullets reduced the drone slightly but the cabin noise was still too unrefined for such a nice car so I started looking for other solutions. Other members had success using J pipes and after talking my exhaust guy into trying them I was amazed at the results. The drone was completely gone and all that was left was a very aggressive throaty exhaust that absolutely roars at WOT. I am completely pleased with the results and do not plan to make any changes to the exhaust anytime soon.

Would you please show us pictures of your exhaust set up, and detailed location and dimension of the J pipe?
Please!

I don't have ramps at my house so I won't be able to get a picture of the x pipe or collector area but I'll try to get a shot of the J pipes and corresponding dimensions. I believe to sweet spot for the J pipe was right around 23" long and they curl up into the void where the stock mufflers used to be.

Looking forward to your J-pipe photo.

Sorry it took so long to get back to you. I kept thinking I would have an opportunity to stop by my buddies shop and get it on the lift and take some better pictures but it never happened.
The circled area and arrow show where the J pipe is split off from the rest of the exhaust. As you can see, it parallels the exhaut pipe for a bit before it curls up into the void where the stock mufflers used to be and is capped at the end. I couldn't really measure the overall length of the J but looked back at some of the other posts regarding this setup and it looks like 29" was the preferred length. I tried to get a better shot of the actual J pipe itself but the rest of the exhaust is blocking it and without it being in the air this is as good as it gets. Hope it helps.

It wasn't that much really because my buddy owns the muffler shop.... I would say from start to finish I was into it for maybe $500 which included the Magnaflow muffler, x pipe, bullets and j pipes. Would guess it would be a couple hundred more if all the labor was included. I also made most of that back when I sold the factory exhaust and stock mufflers that were removed.
