Hey all. Well after looking at the retarded instructions from AEM, I opted to take the car into Honda to get the intake installed. They did a really fantastic job, and only charged me 100 CAD. I probably could have done it myself, but I promised myself way back when that if I got the Si, EVERYTHING would be done pro. So anyways, the intake is so loud....and definately puts a grin on your face when you push the pedal down. It's very quiet in first gear through the rpm range, but then in second....holy friggen loud.
