Finally got the old exchangers off. What a gigantic PITA. I figured they'd fall right off after removing the exhaust stud bolts, but noooooooo. It took about 1 hour of coaxing per side (and a ton of cursing) before they let go.
Here's the old: (IMG:style_emoticons/default/icon8.gif) (IMG:style_emoticons/default/barf.gif) |

i did his same conversion except with non-ss HE's and I felt a difference in performance. I do have a small exhaust leak on the driver side. can't seem to get rid of it. am wondering if maybe the head surface is compromised because i can't get it to seal correctly even with new copper gaskets. I did have to helicoil one stud because one of the old studs came out with the threads...
those ss HE's are nice!! |

In my searches here I've seen both negative and positive posts regarding going the helicoil route. I hate exhaust leaks! |

Yes it is, but I don't think it has anything to do with the helicoil. My exhaust was already leaking on that side with the stock exhaust and it's what drove me to change it out and throw on the older 2.0 setup. Out of all eight exhaust studs on there right now, I have no doubts about the new stud with the helicoil. After seeing their condition, I was tempted to helicoil all of them! |
