First off all credit for this mod goes to "NBR IPD" he posted a thread with the below pictures in the 1LE section. I figured it needed to be shared with all the other LT1 owners since it applies to all LT1 cars.
This is a super easy modification that takes 30 seconds, and can be reversed just as easily if you don't like the sound.
I'm a pretty picky guy and I found that the induction noise this amplifies is a huge improvement and honest to god makes the car sound like it has a CAI installed.
For those of you who have never put a CAI on a car please don't mistake induction noise as an air whooshing sound. The induction noise is the deep bellow/growl you hear on heavy throttle application. I would be shocked if this mod doesn't catch on and become bigger than the typical fuse pull mod.
Now to the good stuff. Below are the photos posted in the other thread that very clearly show where to open up the sound tube and remove the foam insert that dampens the induction noise. Squeeze the collar on the sided to help the tabs on the top and bottom disconnect. Once you open up the tube reach in with a small set of pliers or even a flat head screw driver and pull the foam damper out. After that simply snap the tube back together and go for a drive. If you still have your NPP fuse in you can actually put the car in stealth mode so you can then distinguish which noise is coming from the sound tube. Even without the car in stealth mode the sound difference is very noticeable and if you didn't know better you would think the exhaust had been modified.
Try it out and post back with your opinions.
