I assume you had to give yours up/got tired of swapping back to catted DP, due to the emissions law in your state?
That's exactly why I gave mine up :/ (maybe one day I'll go back once they stop using the sniffer test)

I have a couple of clips on my youtube channel of when I had my muffler delete only. Feel free to check em out.

Not sure if you have the same issue with your muffler delete, but mine would howl at full throttle. I didn't like that.

I did not do the muffler delete. I still use the stock muffler. All I have is the N55 catless downpipe on an otherwise completely stock N55 exhaust system (midpipe with y-pipe + single resonator, and axle-back stock muffler).

I do have the howl @ WOT that you mention. It comes from the front passenger, downpipe area, and floods out the exhaust note completely.
Im not sure if the Vibrant resonators would eliminate that howl. Im probably going to visit a specialized exhaust shop, for their assessment on how to reduce of get rid of that sound, if it is even possible.

The power I gained from the DP + stage 2 agressive PTF custom tune is phenomenal, so I dont want to revert back to stock catted DP.

Ahh. I don't know why I thought you already had a muffler delete. Yeah the power and throttle response from the cat less down pipes can really be felt.
