Hello all,
Wondering if any of you know where to purchase just the exhaust flange for a 73 1.7? This is the rectangular type with two holes. I have a set of SSIs I got for a reasonable price on ebay that need new flanges. I'm not really concerned with getting stainless steel flanges, just something I can weld onto whats there. Would this be overly difficult to fabricate? Do you think a local muffler shop would have them? Thanks! -George |

SSI got cheap with teh 914 HEs and used mild steel on the flanges for a while.
Maybe they used mild steel for the nuts as well. You can weld stainless with mild steel wire it works, not the best choice but it works. Welding mild steel flanges on to stainless pipes is not much different than stainless flanges to stainless pipes with mild wire. Jim |

Yeah, the whole point of this is that I just need to get new flanges on the car. The flanges on the SSI's I ordered are shot, and the headers on the car now are WELDED to the exhaust (flanges were removed at some point). I'm planning on cutting the exhaust, and welding new flanges on the exhaust and the HEs. So all in all, I'll actually need 4 flanges. I think its important to note that this car is never going to be like most of yours. I'm a graduate student just trying to piece the thing back together enough for it to be fun to drive to campus every once in awhile, and to enter a Chumpcar race next year with a few friends of mine. So, doing things on a budget is a prerequisite for me. If anyone has any ideas of how I can create the new flanges out of mild steel, please let me know! Keep in mind, I don't have access to any crazy equipment. Almost forgot. One of the SSI tubes is actually broken inside the exchanger tin. What would be the best way to go about welding this? You think cutting the spot welds, then welding the pipe and then welding it all back together would work? I'll post pictures of it this weekend, after I finish finals tomorrow. -George |

<snip> If anyone has any ideas of how I can create the new flanges out of mild steel, please let me know! Keep in mind, I don't have access to any crazy equipment <snip> Find some one local (no shipping) with old OE HEs or mufflers that that are rusty and cut the flanges off them. <snip> Almost forgot. One of the SSI tubes is actually broken inside the exchanger tin. What would be the best way to go about welding this? <snip> The general thought line of the board is that once the pipe has broken internally they should not be repaired and used as HE anymore. Strip the sheet metal off and weld the pipe but don't enclose the repair. The concern is a possible leak at the repair and introducing carbon monoxide into the passenger compartment while using the heater. We all prefer 914 owners and passenger live thru their 914 experience. Jim |

I'll weigh this one heavily, but I do have a CO meter for the cabin already. Heard that was a purty good idea. |
