Was super easy to install, took about 2 hours (a lot of which was removing the hangers). Looks good, nice polished tips, although one tip doesn't line up perfect but that's just nit picking. It sounds good. I'd say about 25% louder overall. Idle and 1st gear have a nice low growl to them now. Hard acceleration is a bit louder and deeper sounding but hard to tell really. Highway cruising noise didn't increase, which is a plus for me.
Great modest exhaust
If you want an exhaust that is not extremely showy, or too obnoxiously loud, while at the same time being quality then this is the exhaust for you. I spent about two weeks trying find the right exhaust for my 350z, and I couldn't be more pleased with my purchase. The low revs on this exhaust have a deep growl, making it sound like a v8, and the high revs give it a track car sound. Another plus is the fact that it is true dual giving better performance, and it isn't that much larger than stock.
