Buy one now... Do it once do it right... 
I have owned several modified cars since 1994.
Not once did I ever cut / hack / modify the OEM system.. Including my 88' Fox body LX 5.0
Which had Ceramic coated Ford Motorsport shorty headers, BBK H-Pipe & American Thunder Flowmaster Axleback bolt on section with Stainless Steel Finished Tips
Always kept the oem parts prestine for trade in or SMOG if applicable.

So what is have decided I'm going to do after reading a couple more threads and watching some more videos is either remove the resonator, mufflers, or both and replaceven it/them with straight pipes.

if you have aftermarket headers just remove the mufflers and straight pipe it. if you have stock headers remove both.

I had a Y pipe installed where the seconds cats and resonator were for 400$. Did it because I was not patient and getting a system to Canada would have taken longer than having the shop do it in 2 hours. Sounds better but it is still restrictive AF. Winter is here and it's been parked. I will be getting headers and a full system sometime soon, but I would recommend getting a built system. It is tight down there before the mufflers.

[Hey,
I've been meaning to update this thread with a video but I did the Muffler Delete about a week ago and couldn't be happier! Sounds great at acceleration from about 2k-4.5k RPMs. Much higher pitched than I had expected, which I am very happy with.
