repost from exhaust: TTI636vsDougsD450

I have the dougs in my 66 and they are a great header set. I am going to the tti's for my 408 as I think the 3" collector and 1-5/8-1-3/4 step will flow better than the Dougs 2-1/2 collector and 1-5/8 tubes. Drivers side tbar definitly has to come out with the Dougs, I don't know about the tti's. Guess I will find out.
