Is there enough room for a two stage dry sump pump between the case and the muffler? Looks really great.

Very nice Chris. Where do you get your header parts? I need a 4-into-1 collector and can't find anyone who sells one small enough. I also like how you used the bus-style stub tubes. Did you fab those (and the flanges), or does someone supply them? I was going to order some bends and flanges tonight but I'll wait to hear what you have to say.
I'm building a turbo header. (never done this before) -Ben M. |

I buy mandrel bent 180's and cut them to fit in my fixtures. The bends are too complicated for even CNC machinery. Even the collectors are custom made by me. The U-bends come from Hooker through a local wholesaler. The 16ga tube sizes I use are not widely available. The stub pipes are 1 1/2"od T304 stainless tubes tapered up to 1 5/8" at the outlet. Everything else is mild steel. I have several boxes of laser cut flanges, 1 1/2", 1 5/8" and 1 3/4" holes. Try Burns Stainless for a collector. |

Ok, your 914 headers with your phase 9 silencer, How loud is it compared to a bursch muffler, if the Bursch is a 5 (out of 10, which is the loudest) I know you probably have answered this question to death, so if you dont mind one more time....Thanks

Damn.. crazy stuff. I was thinking to myself this evening (where has ChrisF been) no joke.
I see you where busy. Just a quick glance... I only see one bend radius that would be difficult to bend on the CNC tubing benders. So.. 3 out of 4 could be bent easily. B |

Any easy reason why you use mild steel over doing full stainless exhaust for this application ??
I take it your buying the stub tubes already made for you ?? That system does look trick. What length primaries are those ?? Sorry for 20 questions.. it looks good. B |

B, I don't think either of the two right side pipes could be bent using one continuos pipe. The bends are to tightly spaced together along with the rotation that is needed.

A little too loud for a street car, not nearly loud enough for a race car. At Loudon two weeks ago the SCCA sound readings on my race car were 86, 87 dB (about 5000rpm, wot). That's below the street legal maximum in Connecticut. When I got my first 914, I had a muffler (Thunderbird) that was loud. My ears hurt after more than 1/2 hour in the car. I haven't driven a street car much with just a Phase 9, but do I know with the Quiet Can in addition to the Phase 9 I can drive all day no problem. (IMG:style_emoticons/default/MDB2.gif) |

The stainless is actually better for the stubbies though. It is more malleable, so it is easier to taper them 2) I make them from scratch. I have the flanges cut locally. # 2 & 3 are different than # 1 & 4 3)Primaries are around 25" #3 & 4 primaries also have closely spaced bends, but the rotation is less complex. What is the closest spacing you can achieve between bends? I can do 0.0" between bends. |
