Default Anyone with a Fast 90?

I just installed mine and it seems like it is alot louder than the stock one. I mean the air going through it. It is kinda like a howling sound. Is this normal or do I maybe have a problem? I replaced an ls1 intake with it, I added the ls6 coolant lines, but not the valley cover. Is that ok, or should I have changed valley covers? It started right up, Idles and runs fine so I don't think that the noise is a leak, but definitely sounds different

Thanks

Ryan

I just installed mine the other day also and noticed that it was a good bit louder also. More intake noise and a little more valvetrain noise, but she sure does love the added air!

yeah I put the allen bolts in. Just wasn't sure if I needed the ls6 valley cover or not. If it didn't seal well, would it still idle ok? or would it idle real high?
