Just installed this system Friday(thanks Seb for the quick delivery)and all the "hype" is not that at all. When I installed my aluminum fw several months ago I noticed I had lost some bottom end torque but definateley gained power once I got into the higher revs. With the Labree system my Z pulls hard from the time I get on it initially all the way through7k rpm. There is no doubt in my mind this system flows better than the GReddy sp I just sold & the Stillen dual tip muffs I had prior. Thats only half of the story. The tone of the car has changed considerably as well. It has a slight rasp when I get above 3.5k rpm but still retains a deep ballsy tone overall. If you want more power but don't mind the head turning exhaust note I highly reccomend this system. And if you need your car to make less noise I believe they also sell the x-pipe with resonators. Again thanks to Seb & all at Specialty Z for their prompt & knowledgable service.
