I'm having the LSX intake installed on my car. When it was installed the car was started and it sounded very strong then there was a rattling sound. What the heck could this be? This thing has turned out to be a nightmare. Your help is appreciated.

I hope no one dropped anything down one of the ports.

ok, so you had it installed - you fired it up and then you immediately heard the sound ? I just want to make sure I understood what your saying.

Did you watch the install actually take place,
Were the ports covered while the injectors and other items were being transferred from your old intake to the LSX ? All sockets/bolts accounted for ?

Yes to all of the above statements.

THE LSx will transmit more noise...if you had slap or noisy valvetrain...it'll be more pronounced now

This sound was more than a noisey valve train. This was something highly unusual.
