Tried posting this in engine and exhaust forums no luck. Sorry for repeat questions.

Couple Questions

I have a 01 GT Vert and I'm looking to upgrade the exhaust note my car makes at idle. I have the Magnaflow Magnapacks on right now and I love how they sound at WOT but idle they're too quiet for my tastes.
I want my car to sound like this at idle: http://youtube.com/watch?v=BWx-XeaNMaY

I know I'm going to need some aggressive cams, heads, longtubes, and a nice midpipe (thinking of prochamber) and I want to stick with the cats I have now.

1. First question is I'm looking at the the Crower Stage 3 and 4 Cams. They say rough idle for the stage 4 and "lope at idle" for stage 3. What exactly does "rough idle" and "lope" mean?

2. Also, it says the rpm range will be 2000-6900 for stage 3 and 2250-7000+ for stage 4. Does that mean I'll need to get some sort of device that makes it so that in order not to stall out I need to be at 2000+ rpms at all times?

3. If I do end up going with the stage 3 or 4 cams what other things are required besides new valve springs?

Thanks in advance

lol, didn't you just ask these questions?

Anyways, Lope is the ticking sound you hear in the video while the car is idling as for the rough idle that means it'll be a pretty mean lope (rough sounding at idle) and as for the RPM's that's when they start to give performance gains within those rpm's
