Hooker,doug's,TTI?

I am getting ready to pull the trigger on a set of headers ,I am curious to know who has installed hookers and how did they fit ?
They will be going into my 64 Barracuda with a 360 and automatic with manual steering.
As far as Doug's and TTI's ,I have read some of your posts, so I know where they stand , next would be looking for the best deal.
Looking for chassis exit as I will not be using fender well.​
How radical is your engine. For my money- unless you have a high rpm motor- you are better off with stock manifolds. May cost you some horse power over 5000 rpm, but may even give you more low end torque for a street ride. Less problems with leaks, and definitely cheaper....
