My 73 914-2.0's HEs are original & now rusted through, so I picked up a pair of good used SSI HE's/exhaust pipes to not have that problem & CO poisoning issues ever again! (IMG:style_emoticons/default/icon8.gif)
My question is - should I leave them shiny, or paint them as per the stock OE mild steel ones, or does it matter in the CW world?? (IMG:style_emoticons/default/confused24.gif) If painted, is it the same flat gray hi-temp paint as used on the mufflers, as seen at the 356 Registry?? (IMG:style_emoticons/default/confused24.gif) They look like this now: Thanx for your input! (IMG:style_emoticons/default/beerchug.gif) |

Don't be fooled into thinking those are permanent, as they fail too!
I'd blast them with walnut shells and they'd look new! |

Actually, these are about as permanent as you can get, providing the end seasl remain intact. Remember, there are ferrous tubes inside the stainless shells. The seals for these "can" fail, allowing oxidation to enter & take its toll on the exhaust tubes, leading to potential failure. I, personally, have never seen any SSI's fail, from an interior point of view. The sealants they used for the ends of mine are as new, after more than 30 years. I'd be curious to know how nut blasting would solve anything, since the only areas of cocern are inside the SS shiekds? Pat |

(IMG:style_emoticons/default/av-943.gif) Pat - you kill me! (IMG:style_emoticons/default/lol-2.gif) I do have some old oil crust on the inside end of one of the cases that I'll need to clean out, probably from the PO's oil leak seeping into incompletely or improperly attached heater/air tubes. It probably won't require "nut blasting"! (IMG:style_emoticons/default/biggrin.gif) |
