Hey Chris, I'm going to try the 2087 pipe with the 204 header on my C6, my carb settings now are HSN 2 1/2 out, my LSN 5 out with the 2045/192 pipe. I know that I will need to out both needles, would you know approximately how much on each? I want to get a more linear throttle response, a little less bottom as the 2045/192.
