I took off the the top of the airbox and popped the bottom out of the fender wall. I took a good, sharp 2" hole saw and cut 5 or six holes around the perimeter of the lower half of the box--not the top. Big difference in response now and I get a little more growl with the Dynomax exhaust. Using a K&N filter and am building a homemade induction out of PVC (a few threads on it). Next will be the Granatelli MAF and Edelbrock throttlebody. I'll stop there--unless I have to get a new engine. Bilsteins are monotube shocks (229 a set @shox.com)so they ride stiffer and have better response but many like to keep the twin tubes for a little more comfort on rough roads and city driving.
