Installed 3" connect Mak cat delete over the weekend, along with Magnaflow resonators. I already had MBRP street factory connect, so we cut the 2.5 section out making this a true 3" system from the header back.
We used Vband clamps so we can reinstalled the Cats easily for emissions. The pic below is where the H pipe meets the new catless downpipes.
A close up of the Magnaflow resonators. I don't believe they are doing much for volume, but they are killer for rasp. This new system has less rasp even with the cats removed than it had with them.
Picture of the new system, pretty damn sexy if I do say so myself.

Taking the stock cats off and looking at the crimps in the pipes that looks closer to 2" you can really see where the performance gains are going to come from. Its amazing that guys are making 700whp with them. The car feels much strong and the rev's build quicker. Very happy with the performance of this mod.
The car sounds awesome, but its too loud. Cruising and idle are fine but acceleration is markedly louder. Cold start and WOT is REALLY loud. Time will tell if I live with this or take steps to tone it down. Although I don't think the resonators did much for volume they did make the tone much more pleasant. These types of resonators are great for someone not looking to quiet the system much but rather smooth out the tone.
I actually had a pair of Magnaflow 12229 mufflers on hand which I expect to sound like the street set up but I didn't pull the trigger because I am doubting that they will quiet down the exhaust enough.
Unless I find a much quieter muffler it might be an ad hoc variable system for me.
