I said both sides thinking you were putting the stock manifold back on and didnt want a leak on either side. but just go ahead and cap off the one side and you are good to go! The new exhaust headers will either A) Have NO SPOT for that emissions pipe to go in or B) Have that hole and have a plug in it already.
So as long as you plug that ONE END of the pipe sticking out on the exhaust side, you are good to go!
