So I installed my cobb sri yesterday and I have to say that it's a well built intake. Cobb put a lot of thought into designing this intake and it looks a lot better sitting in my engine than the old air filter. First driving impression is that the car felt a little more aggressive than before. The intake adds to the solid feel that I've been looking for. Plus having that blow off sound is an extra plus! I did have a question for you guys that have the cobb installed. It seems like the air build up in the intake sounds different than what most intakes sound like. It sounds like someone is letting helium out of a hot air balloon. I don't know if this is the way an SRI is supposed to sound. I had an AEM CAI on my last car and it sounded more aggressive. Is there a way to get a more aggressive sound? What do you guys think?
