Let me say this on one of my old c5 set up's ls2 402 ci with a YSI on it I went from a LG 1 7/8 header set up to a KOOK 2 inch header and lost hp all thur the rpm range until I got to about 6600 rpm then got it back but only 6 hp on the same dyno but it was diff days.
I also on this set was running a trick flow 225 head that BT did some work on also. Also same cam in the car and all of that.

Buddy I think you will drop in power with no more ci & head size at that power level. Now if you say 427 ci & a 245 to 265 heads with a F1X blower & going to look for 1100 to 1300 rwhp then yes I would.

you will lose zero down low from a 2'' over a 1 7/8. We have proven it many times over, you did a good thing getting a 2''.
