I decided to start on my TRD Headers today, even though it was 106 degrees outside. I almost got the stock manifolds off, in the 2 hours I was out there. I gave up trying to get the bolts off of the y-pipe, so took everyones advise and just got out the saw-all. I have one more cut to make, and the stock pipes will be out!
I would like to get the Headers in tomarrow, but we will see.... wish me luck on the rest!
