What are the specs on the B & B headers and do they have cats? What price are you wanting? Also how do the specs of the Fabspeed compare to that of the B & B? Do you have pics of the B & B?

I think Todd is going to have the best advice hear seeing as he's actually done this engine swap. Thank you Todd for giving us the info, it is appreciated!

I'm just going to throw in my 2 cents... You might want to give Instant G a call. They specifically make an aftermarket exhaust system for the 3.4 L Boxster conversion. From their website it sounds like it's pretty oversized for the application, so it may work well for a 3.6L too. I'd ask them. Plus they may be willing to make something to fit your car as they appear to be a small, custom order type of operation. I think their 3.4L system is about $3,000 complete (headers, mid-pipes, and muffler), so it's not cheap, but the quality and design appear to be top notch.

Here's their main site:

Looks good but not crazy about that flat triangle collector.

I called B & B about an hour ago. I asked about the Cayman header they sell as fitting the 986 w/ 3.6L He didn’t think it would fit with out cutting it up and re-fabbing it. He thought that a custom set from scratch was the right answer if you have the equipment to do it. I do so I think I’m going that route.

He gave me the place where they buy their components to build stainless mandrel bent headers. They sell collectors, flanges and all the stuff to build a really quality set of headers. I would like the best size primary diameter and length to have it work as good as possible. They have many different high quality 3 into 1 collectors too. They sell 321 and 304 stainless parts. I have a mill, band saws, drill press, tig welder, torches, and other metal working tools to get it done.

I can't believe people. Go and believe someone who hasn't done it. Just because I have put a full Cayman B&B setup on one car and a combination of cayman Fabspeed and Supersprint on another, I guess it can't be done without a bunch of fab'ing. Please stop wasting my time.

I found an interesting header for the Boxster 987 / Cayman at Design911. It looks pretty well designed and would flow well and it has cats. Not a lot of specs on it yet and the price is high. This header like a lot of them are more of a true exhaust manifold than a header with very short primary pipes, not really taking the need for the correct length and diameter into consideration for all out engine performance.

I really like the B&B header and a person could mount a set of cats somewhere else down stream. The folks at B&B were interested in quality and performance both. They did not try to up-sale me on anything, but tried to steer me in the direction that they thought the best for what I was trying to do. I really appreciate a company like that. Without hesitation they told me where they buy the parts that they use and I could do it myself and a more of a one-off cost effective way.

Here is the link to Bill Boat Performance Exhaust (B&B) I couldn't copy there pic of the Cayman header and post it here or at least I didn't know how too.
