Nice work!
Any details on the little tube fixtures? I assume you're back purging while welding correct? Again, nice work. Tim K |

you sir , have skills , there are many here who would pay dearly for those , they are a work of art , almost a shame to put on the bottom of a motor ....
one idea is to carry a couple of mirrors and put them down when you park to show off your work ... truly nice . |

Nice!
"Build my own?" Yeah, right. I would have better luck doing my own open heart surgery. |

Hard to see the clearances in the pics, but could you sharpen the bend in the middle pipe and move it down enough to take an inch off where it meets the head?

You'' probably need a bigger flange where the exit the heads - but excellent work there my friend. How much?

Very nice!
What muffler are you using? Is it a straight through? Hoping it is not an X flow muffler. |

Your primary tube design is similar to mine. Back purge is not as critical in a non-turbo application but you would not want to suck in any slag during decel. I assume you are welding this up.

All,
The "kit" I used was purchased from a company called "icengineworks" it came with dozens of various pieces (different radius & straights) and the welding clamps you see in the pictures. It took me about a week and several attemps before I got them to fit & equal length. The muffler is a Magnafold "X" flow type at about 14" wide. Somebody said the "x" flow may not be good?? and I think I could have gone with something wider (like 20" wide) and thus less loud?? Any suggestions on olive connector or straight flange type after the merge collector??

This it my belief or two cents on the X flow. It was not intended to be used with exhaust gasses coming at each other where the tubes cross. It is more intended as a cross over and muffler for a car with a V6/8 where the tubes and gasses are running the same direction.
If you are intent on a Magniflow style muffler there is one that has two straight through tubes. This has been used with one side of the motor going through the upper passage and the other thought the lower tube in and out. They also make a Camaro muffler that has two 2.25" In's on each end and one 2.5" out on one end. Your design is perfect for a Flowmaster muffler which is designed with an In and Out on both ends of the can. It is a proven race muffler on a 911 and makes power but can drone with its two tail pipes. |

just check out
Ice engine works Probably cheaper to use some mild tube for mock up.. It modeling blocks...Ideally you use sections of off the shelf tubing....
