Stillen Exhaust tips just the same as original ?

[hedly]

HI guys....This is my first post - as I am soon to be the owner of a new 370Z inc Sport Package. I take delivery in a couple of days. I had the opportunity to test drive the Nismo for few hours -one of the first here in the Great White North. I loved the car - dealer was motivated to move it....could not get past that rear deck spoiler. Amongst a lot of other things..The exhaust tone was sweet (Nismo) and added that bonus of extra HP. So as an alternative, I'm working a deal to upgrade the standard exhaust on the car I have ordered and was leaning towards the Nismo kit. Price was pretty steep and delivery - TBA. None in stock special order money up front did not help. The alternative offered was the Stillen. Now I've spent a lot of time searching the forums and it seems a good choice. Extra HP ( most important ) with a bonus for me of not being overly loud. I currently drive a G35 coupe but not that crazy on the fart can resonance that car produces.

So - First question - good choice going with Stillen ? Any thing I should be aware of like once driving the car will the exhaust sound be resonating at some low frequency my hearing will be gone ?

Second question - Do the exhaust tips line up with the rear bumper just like stock ? do they extend out the back more than stock ? If they do can that be adjusted ? I can't find any pictures of the exhaust tips from the sides - only straight on from the back.

Last question - do the mufflers hang any lower ( from behind ) than stock ? do you see those big stainless steel cans when following behind a Z with Stillen exhaust ?

Thanks for anything you can share....
