KTiM, If you have a line to Sommer, ask them what is wrong with just widening the hole under the snorkle about as much as the side airbox mod. But it sounds like I should open it a little more than that if you think the snorkle should come out too on my '03. I could always turn the snorkle around for that ram ain hood scoop effect! creeper, I know I need to do some type of airbox mod before installing the pipe. And I guess I need to rejet, especially since I dont have the quiet core yet... (PASSMORE!!! wassup?) You really dont think opening up the passage under the snorkle is a good idea? I don't have the stuff for a side airbox cover mod and I can probably sneak a few carb jets under the radar of mrs. popsicle... but she is not really happy about the pipe to begin with.
