Ordering a new aftermarket air system for my lb7 which is going to be the best system for my truck was looking to spen around 250-300 and also I hate not being able to hear the turbo and I also want a little better gas milage.
I also did the airbox mod and am happy with it but it did not do much for anymore whistle.I did the swiss cheeze on my LB7 and it worked better than the rest.

I herd alot of pepole are happy with Bills custome intake and they say it whistles much more.
And if your looking for maximum whistle out of the factory turbo from what I read this is the hot set up.
Bills custome 4" intake.
