The Bend's

The Bend's What is the degree of bend for the driver side pipe when it exits the header? Any idea?
Notice that the headers kick out to the left on the driver side header but is straight on the passeger side header. What is the degree of deflection, for the Y pipe? I need to know for a custom exhaust fabrication.
Cheers!

What I'm doing is fabbing a new exhaust from the headers back in 3" oval tubing. The drivers side header turns to the outside a small degree, I need to know what that degree of bend is so I can turn it back straight and run my piping.
You say that is 12 - 15 degrees? Is this a guess or a soild measurement? I am getting the pipe from SpinTech, been thinking about sending them a piece of the factory Y pipe and have them make a piece with the same degree of bend out of 3" oval.

I went ahead and ordered a 15* bend and will see where that ends up, I'm thinking I can massage it into place without much trouble.
Ron from SpinTech said to get the 15* and cut the ends off to make it match if its too much or not enough. He said he would put some directions in the box for me to show me what to do. I like doing buisness with him, straight up guy with no BS.
I hope to get my new motor fired this weekend. I built a Darton Sleeved 427 with all the supporting Go Fast parts and hope to be making almost 600 at the wheels naturally. When I start putting the exhaust together I will post up pics as I go, I plan on doing all of the welding myself.
It will be a true dual system, no H, X or Y pipe, 3" oval pipe to dual 3" oval mufflers transitioning to round over the axels and straight out the back slash cut. I chose oval tubing becasue the car is lowered and oval tubing gives me an additional 3/4" of ground clearence.
Thanks for the help OMC8!!

Not needed for the HP I am going to make.
"The X pipe works best on a V8 engine running 300-500 hp because the volumetric efficiency is not as great as on a 700-800 hp V8 engine"
Copied that statement from an article in Corvette Forums.
My motor should make between 700 & 800 at the crank, so roughly 600 at the wheels. I have done some research and really havent found anything that says (for my HP) that an X pipe would be beneficial to my setup.
Plus that's another $200

I don't know the normal angle, not the best one,
but I observe that every Y I've had other than the
stocker, has had one that's slightly wrong (if you
like a nice tuck-up and no banging).
I would advise you to think about multi-sectioning
it and using V-band clamps, or flanging it and making
the final angle rotations on-car and then tacking the
flanges in position. I don't think giving the bending
machine or the bending dude a number, has a very
good chance of first pass success.

Found this article from Car Craft magazine talking about X Pipes.
http://www.carcraft.com/techarticles..._installation/
They were running straight headers and had Magnaflow install a stepped exhaust system with a X pipe and had the same power as straight headers but a whole lot quieter.
I'm not opposed to running an X pipe, just thinking about room and cost.
I aggree JimmyBlue, I plan on doing much of what you wrote. Thanks for the input!

Yes it did, I guess they made a custom one for the project. And yes, interesting article for sure. Makes me reconsider my position. I think my setup will be noisy as hell, this might be a good way to tone it down a few decibles.
When I pull up to the Clubhouse in the car to play golf I bet its gonna rattle the windows, golfers may not appreciate that, especially the Ford golfers!!

That was an interesting article. So they had a 3" collector necked it down to 2 1/2" to the X, stepped it up tp 3 1/2" for 26" and then necked it back down to 3". I aint never seen anything like it before. And does the X on the car look way different than the one in the photo to you?
