PPL with dual exhaust?

I was wondering, for those of you that have turndowns underneath the floorpan, I guess most of you are running bullets, but do you get any resonance that is quite annoying? Right now I'm dumping straight pipe just by the rear bumper and I can barely hear the stereo over it when I get on the throttle.

I plan on installing some sound deadener, but at the moment that will have to wait.

Here is what I was planning to do...

It basically dumps right where the passenger side rear seat is, I might angle the turndowns towards the outside of the car to redirect some of the sound.

I figured my parts list would be something like...
MAC 96-97 Y Pipe
Catco Convertors
Dr. Gas X Pipe
Bullet Mufflers
Turn Downs

I would have somebody across the street weld it all up for me and it would pretty much be a bolt in operation.

But like I said, my main concern is interior resonance, if its "that" bad, I might as well just run full piping to the rear, but I want to make it a simple installation.

Thanks
