Awesome, I plan to try using the stock Y with the rebuild. I indeed have my stock system but its at my parents house 1300 miles away so if shipping costs are not too high, i'll have it sent. As for the rush header "reaction" to the stock Y, I feel that the system will give much better throttle response because its going to be flowing more cfm at any given rpm, so the engine will still be within the stock Y's limits flow wise and a little closer to the vvt engine class overall. Once I get to thge point where I rebuild the engine for 11:1 or 12:1 cr, I may see a need to create a slightly larger nozzle but for now im sure it will work great.

Most mufflers slip OVER the pipe feeding them. Check the internal diameter (ID) of one of your Magnaflows
