Nope, I wouldn't do it. Your O2' are going to go "Loco" if you kept them. If not the total lack of backressure will give you a hell of headache with tuning and misbehaviour on the part of that LS1. I would run at least 1.5 meters of tubes with an H pipe.

ok guys thanks for the advice,ill be sure to pass it along to him.i had a feeling that it wouldnt be the best idea to drive around like that,but i just wanted a second opinion from you guys that have been there done that.im trying to get him to do an x-pipe setup,so we'll see if he wants to go for that.for now though i think he'll live with open y pipe.he already drives around now with the stock exhaust off after the y.
