Interesting... More than one person there was making 20-24 rwhp on that exhaust before and after dyno results.
I checked the stillen website and the exhaust for the 350z was 16hp.

So couldnt be that hitech make a pretty decent exhaust..
Looking forward to see what they bring out for the 370

Another big positive is that the cat back system is between $1500 - $1800 ( pretty sure that is installed). So at this stage I'm leaning this way on the exhaust system.
