Which would work better on a 65, 289, 4bbl, automatic, this motor will have 300 - 325 horse and will be in a 65 2+2 fastback. Which will give me more extra ponies in the 289? What are the advantages and disadvantages of each ? I will be going by your recomendations as to which one to put on the car. I had one guy tell me, not to use either, just run the system from exhaust manifold straight back to the muffler then to the tail pipe, not to meld the two pipes together. I am not sure which mufflers to go with , but , kinda leaning towards flowmaster, what are your thoughts on this ? Thanks in advance to all of you for your input to these questions

Well I like the H-pipe,but I also like big as$ scoops on classic stangs.
I have always read and been told that the H-pipe will give you little more low end.But I know for sure that some of the others guys have other opinions.

This was discussed rather fully just a while ago. Check this thread for details:

For what it's worth, I've been reading everything I can on this subject for months (including here at M&M), and at the end of the day I'm going to stick with straight pipes. SteveW is just too convincing!

There's a good article in a recent Hot Rod magazine where they test a hi 10 second street car with open headers, h-pipe with muffs, and x pipe with muffs. The x-pipe was quickest of all three! (even open headers)
A friend of mine runs an xpipe on his 67 camaro, and it scavenged so well that it was cherrying the headers. I know he had to change some things in response to this, but the end result is the car ran better.
