I agree, Fast Intentions make a great exhaust system. I have one on my G37 coupe. It sounds amazing, not annoying, raspy, or too loud. It does tend to get a few head turns when I run up to the higher rpm's, but I've never been stopped for it, I have tested that a few times to see if it'll raise the hackles on the local constabulary, not an issue to date. It may cost a bit more than other setups, but it's worth the cash. I like the fact that you can get it with or with out resonators and they offer different sizes for the resonators too. I went the "with out" route. I also polished the cans. It's kewl that you can see them from behind, so a lil elbow grease pays off. I'm going to put a F.I. exhaust on my 370 Z roadster too.
