Last I heard they fixed the issues with the first batch. They are good for stock but they are 1-3/8" OD tubing, so a major restriction for any bigger or higher HP than stock app.
I've got a 3.0 perfomance engine, as much as I want heat stock HE's would be a hugh step backwards for me. |

I've also heard that the fitment problems have been fixed, and that they are (or were being) shipped with jigs bolted in place.
With that said, and as much as I like their correct appearance (for all those times I'm under my car these days... (IMG:style_emoticons/default/unsure.gif) ), I'd have to go with @mb911's HEs. Superior materials, beautiful craftsmanship, and a choice in pipe diameter, ability to have bungs for 02 sensors added, etc. |

Stoddards, RD etc., made by Dansk IIRC, they make the new /4 SSI's and for the 911 SSI as well. Not new porsche, but OE quality copy from a Porsche supplier. They bought SSI. |

At $3700 that is an incredible amount of money for a sub par collector but it does fit the oem look.. shoot mine are $2200 and now use a f1 merge collector and they are still a bunch of money

Last year, I saw a set at the Stoddard booth at the Phoenix club. They look just like the factory one's but were missing some of the screw tabs. They are only useful for stock 2.0 engines maybe a 2.2? My 3.2 ran night and day better when I switched from the stock six heat exchangers to Ben's (MB911) 1 5/8th's heat exchangers. I think stock is like 1 1/4"?

Original factory HE's will work on mild 3.0's but you're giving up top end power and getting a bit more low end torque. Bruce Anderson told me that the 3.0 referenced in his book to get over 200hp was using 914-6 heat exchangers.
If you do more aggressive cams or bigger carbs, stock HE's are too small. |

OK...thanks very much for the pics and info.
I know it has a lot to do with gas extraction of the pulses of each cylinder in the firing order etc etc.. Not trying to get into the theory and such. I've read a little on it until my head hurts (IMG:style_emoticons/default/smile.gif) Are there any clearance issues with this type on the 914? Any dyno comparisons. Thanks... |

Marty at MSDS uses a similar collector, no clearance issues. Ben's the only real game in town if you need big /6 pipes and heat, and that they're well made is the bonus. The repop heat exchangers are a reasonable facsimile if you're building a stock 2.0 914/6. |

I'm lucky to have some excellent originals but wanted to know the state of affairs if / when I don't. The repros appear to be missing a couple original attachments. $3700. ! With a 3.0 in my future heat + performance = aftermarket.....it's great there is a quality cost effective alternative. Thanks all |

Thanks all Unless it’s a concours original 914-6, I wouldn’t waste my money on 1 1/4” heat exchangers on a motor bigger than a 2.4. When I installed my first 2.7 six in my 914 back in 1987, Marty at MSDS recommended his 1 5/8” headers and muffler. That car with PMO 40 Weber’s ran awesome! That engine revved up faster than I could blip the throttle. Good times!! The B&B 1 5/8” heat exchangers produce little heat and the quality is not consistent. I have seen crooked pipes which produces a crooked muffler. Bens 1 5/8” SS heat exchangers produced the same amount of heat as the stock heat exchangers and runs much better on my current euro stock 3.2. |

Yeah, the B&B are a waste of money. Every set I have seen look poorly made. For the life of me I can't figure out why PMS uses them on their large motor builds. For me, Ben's @mb911 heat exchangers and mufflers are the ticket.
