both the same. the AFE is a direct fit. with the LBZ you have to cut the intake tube back for it to fit

I got the afe and I love it. Yes the LBZ is cheaper but I did not what to hack things up to get it to fit. Don't hesitate to change the mp, it makes a huge difference in the performance of the lly.

Blocking resonator is for so much more than sound. It is to block recirculating soot back into you motor! LoL

you got me!
I re-read my post and it sounded rude. I do appologize if you took it that way. It wasn't meant as a jab towards anyone.

You are correct. I didn't notice anything other than my oil being a tiny bit clearer between service intervals. The mouthpiece on the other hand will make the turbo spool quicker and it will also enhance the whistling noise as well. If you want to further enhance the whistle and get rid of some of the screetching noise upon hard accelleration i would recommend the DE direct pipe. It is on my to do list as well as upgrading from a modded LLY mouthpiece to an AFE!
