Technically, it's a Short Ram Intake (it doesn't scope down a couple feet like a CAI). And I JUST did the same mod to my ST and I was thinking to myself how very little it altered the sound of the car. I guess that's good, because I KNOW that the header I plan on getting, even coupled with a stealth exhaust, is gonna make the car louder, lol.
Nice launch squealie, BTW. I'm guessing you don't have a sport tire, though, or else it would probably hook up a little sooner. My car was sold to me with some BFG something or others. They were low profile and man, did they hook up nicely and held corners really well. But I had to ditch 'em with about 50% treadlife when I found out how they struggled in bad weather. Now I run Michelin Pilot Exalto A/S (supposedly a high performance A/S) in the warm weather. They're great in the bad weather, but they don't hook up as quickly as the BFGs did, that's for sure.
