You'll need the 1 5/8 inch size. For a great product contact Marty at MSDS. I think he is in the vendor forum. If not, he is in the Pasadena area if I recall.
He has beautiful ceramic coated headers for a good price. |

I have 1 5/8 on my big port 3.0 that I purchased from a Brumos Porsche swap meet a few years ago. That size seems to be a good compromise of torque vs. horsepower. I had them ceramic coated and that is the way to go for a finish. Depending on the header length you may have to add extension pieces to have enough length to meet the muffler.

Hey John,
I see you are making the same decisions I am struggling with. I was kind of hoping in the back of my mind that I could use my factory heat exchangers but it seems like that won't really work with out a pretty significant loss of power I guess. If I go with headers on my car I will go with the ones with the heat exchangers as I do want a heater in my car that works like the stock one. I definitely like the jet hot coating finish. I would like to be able to use a stock muffler, I have one still in the box, but don't know if that will be possible for the same reason as the heat exchangers. Oh well, time will tell. It was nice to hear Jeff's engine run (on the video). See ya, Michael |

1 5/8" for 3.2. (edited. I misread the engine size as 3.6.)

I would measure the ID of the stock 911 system and match that for a street car.

If you don't feel much difference, you've saved yourself a ton of money and effort. Plus, I'm curious what will work on my engine. (IMG:style_emoticons/default/biggrin.gif) |

John (IMG:style_emoticons/default/driving.gif) For a stock 3.2, 1 5/8" will definitely provide the most torque. |

I run factory heat exchangers on my 3.2. It runs great and has alot more power than my 2.7 did with 1 5/8" headers. That being said I have not tried 1 5/8" headers on my 3.2 so I don't know what I'm missing.
I am also running Bursch quiet muffler. |

Hey Mike , I finally found one it should be here next week, The guy's taking his time, I put a deposit on it a week ago and is suppose to have it sent by Tuesday, Its a 84 3.2 that's been re-sealed and valves done and adjusted compression numbers are #1-171/5%, #2-169/4%,#3 170/5%, #4169/4%, #5-170/6%, #6-168/3% also the driver side tensionner was replaced all this was done 3k mile's ago. Geri's not happy with me right now she wanted half the money from the boat sell, but I'm spending it before she take's any, which mean's no loving for awhile and will be making my own lunches and meal's. But I hope she's just making me fell bad she made me dinner last night. Now I have to start the build I have been collecting for a year now, the motor was the last big part needed. Thanks Guy's for the input, this is the greatest place for information. Thanks John (IMG:style_emoticons/default/driving.gif)
