It looks good. I think it added a bit of power according to butt dyno and wheel spin. Tough to tell though. I'm getting a very raspy sound at a couple points thru the RPM range. Not too keen on that.

Happens to mine too. I'm guessing its the resonance frequency of the air flowing up the pipe. Not much can be done to fix it. It tends to vibrate a little more at those 2 spots. I put some thick foam between the frame rail and the intake pipe down by the filter and that helped some.

Right around 3000 and again at 6k?

Rep Power: 306 You guys with the resonance issues. . . which exhaust systems are you running?
The day after I installed my Injen CAI I installed my DC TCS system. At around 3K it does resonate a bit more, but the exhaust note is badass. I'm just wondering what kind of backpressure might be affecting the resonance frequency of your intake.

Rep Power: 423 I still have the stock peashooter for an exhaust. I haven't listened to the exhaust note, because I tend to be driving it when it's doing this, and all I hear is the intake.

Rep Power: 306 Ahhhh, okay.
I drove my car for just one day between installing the intake and the exhaust. I probably didn't do enough actual driving to realize this. It's quite possible that relieving some backpressure might help this oddity. [IMG]i/expressions/face-icon-small-confused.gif[/IMG]
I did notice that when putting a good load on the engine (acceleration) that it did become notably louder. Now that I have the TCS exhaust on there, the resonance might still be ocurring, but could be masked by the very throaty exhaust note. I'll have someone else drive my car for a few and see if I can hear any rhaspiness from outside the car.
I'll update, soon. If I don't hear it get rhaspy, then an exhaust might help.
