Dude, I have been F/I for a year and a half and have gained enough knowledge about this kind of stuff to not need your comments. I didnt ask for your comments and neither did the OP, so I would appreciate if you would shut your mouth until I or someone asks you to talk to them. If you have something that is helpful to the OP, then by all means speak it. But if all you are going to do is downplay what I have said, please keep your comments to yourself. This is my last post in regards to your BS comments so if you respond again, it will fall to deaf ears! Have a wonderful day!

 

I have an ATI and trsut me it rattles worse.
on a parking lot people turn look and if I ahd a dollar for every time I heard "Dude whats wrong with your Motor?

 

It was not very hard to do. Just start at one end and cut the pipes bit by bit to make them have a nice fit. At the bend I used the polished pipe (from the old Injen CAI) and slide the rubber pipe over the ends to make the connection. I wanted something solid at the bend to make sure there is not suction on the pipe when pulling lots of air. As for the noise. I don't think it made to much of a difference. My kit has never really been that bad, and when I put the 3.12 pulley on, it seems to make it a little quitter. Might have just been my imagination. The idle increase really helps though.

 

Can anyone else comment on it getting quieter with a smaller pulley?

 

It might have seemed different becasue the 3.12 pulley that I got was a much tighter fit. For some reason the 3.33 with the pin in it still had some movement. Like I said most likely my imagination. When I get a chance this week i'll see if I can get a sound clip for you guys.
