<h1 align="left"><u><strong>How To Make a Merge Pipe.</strong></u></h1>
</div>
<br />
So started this and got most of the way done and my computer froze so I have to start over. So sorry if this is brief. <br />
<br />
This is the start of my manifold for my 420a.<br />
<br />
I got all of my steel from Ace Stainless... 2 feet of 1.5 inch Stainless Steel Pipe.<br />
The flange was purchased through FastWayRacer.com<br />
<br />
First thing first. Your going to want to estimate the size of the Merge Collector. I cut my pipe to 5 inches. <br />
It was a bit long but its easier to cut steel than make it longer.<br />
<u> </u><br />
<br />
My cuts were cut at a 60 degree angle. I would suggest more but my bandsaw only cuts up to 60 degrees. <br />
After your first cuts you will turn the pipe 90 degrees and perform another cut. Its very simple once you get everything lined up. <br />
Here is what you should end up with after you do your cuts. <br />

<br />
Now you are going to want to tack 2 pieces together. Do this for both sides. Should look like this....<br />

<br />
Next your going to have to do some fitment. The cuts that connect the 2 side pieces together to<br />
make 1 big piece, dont line up perfectly. I pulled out the grinder, and grinded them down until the<br />
gap was small. The smaller the gap the better the weld. This is where I suggest cutting the pipe shorter. <br />
It will be much much easier to do the 2 pieces instead of 4. <br />
<br />
Now weld them all together. MAKE SURE TO USE A TIG! <br />
You will regret it later if you dont. If you dont have a TIG pay someone to do it!<br />

<br />
Now your basically just going to place it on the flange. Keep in mind bolt holes. <br />
Your not going to want to get it all welded together and then realize that you cant drop bolts into it. <br />
