Long tube headers with factory exhaust?

[br549]

I just bought my cts-v coupe. I put a cold air intake w/ k&n filter, I would like to put long tube headers & connect them to factory mufflers. 1. Does anyone sell long tube headers I can buy to do this? 2. Does anyone know what size the factory pipes are 2.5" or 3" ? Thanks Phillip
