My 3.2 had aluminum tubes 4 pieces for each tube, the o rings were shot and the ends came off the tubes when i removed them, I jb welded them back together and got new orings. I will replace them with the steel ones because they are starting to leak again. Silicone grease works good to make them slide. No heat exchanger removal neccesary it is just a bit harder on the left side. My first repair lasted about 3 years.

Lube definitely will help. I have done this many times prior to my build.
You don't need braun but as in all of our Porsche tasks, the proper tools or improvise the tools. Get two BFS's and equally pry the leaking offenders off after removal of the circlips, use electrical tape if you worry about marring the case of tubes then get some matching pry bars and two clamps the same ID as the OD of the tubes. Place the clamps where they need to be so the pry bars can press out and the tubes into the case and heads. I swear they will simply plop right in. Leak Free. Don't forget the circlip :D http://www.harborfreight.com/media/c...mage_11209.jpg https://www.belmetric.com/images/CA1...ue%20Clamp.jpg Removing the Heat Exchangers makes it even easier. :D |

^^^Easy-peeezy with the exhaust removed. My comments were made to assist sugarwood with his decision based on his exhaust being on the car (as he wrote he has rusty studs). I don't know how much room B&B headers offer, but if it's anything like a stock heat exchanger it's a tight fit.
Tube quality. Aluminum tubes are not the cat's meow because they are made from pieces that are assembled with epoxy. At my shop we preferred the tubes sold at Porsche, where each section is a single, formed, piece. Anytime I can use a replacement part that has fewer opportunities to fail that's the part for me. |

I like sugarwood. He is a righteous dude. Leghorn award presented for valve lash. Upgraded to the rare Darth Leghorn award for actually attempting to remove his exhaust in a subsequent effort. |
