Crustysarge, what type of rust? Rust that happens over time caused by moister in the header, or outside rust that is caused by a bad coating. The rust you have looks like a coating problem not a old age rust problem. If that makes any sense to you. Ask a lawyer about it he will do a free consultation.

Your headers might not be rusting. I had the Hooker Super Competition header and side pipe exhaust system on my old 1982 Corvette, which was Jet Hot coated in the same sterling finish as yours. I had the same "rust" stains appear on my side tubes and collectors. It turns out the "rust" was actually road slush baked on. Anytime I drove the car in the rain, hit a pothole with water, etc., the stains would appear. When the dirty water hit the headers and side pipes, the heat from the exhaust boiled away the water and the dirt/oil was left in the form of a stain, which looked just like rust. I found Mother's aluminum polish took the stains right out and kept the coated parts shiny. Now if your finish starts to bubble, then I would send them back for a re-coat. It looks like most of your stains are the same as what I had, but the area in between the collector tubes appear to not have sufficient ceramic coverage, thus causing actual rusting in that particular area.
In my opinion, the ceramic finish is well wort the money. Header paint will only protect the outside of the tube, not the inside, thus allowing them to rust inside and outward. Ceramic finishes are applied inside and outside the header, which not only protect the metal from corrosion, but also retains the exhaust heat in the tube, thus reducing under hood temperatures and preventing exhaust heat damage to rubber and plastic parts under the hood over time. |

Going from d-ports to round ports, NOT an option.

Mine did show some rust specs where all four tubes come together at the collector and showed what looked like slight surface rust at the flange before I even fired up the engine. My car sits outside on a cement slab under a car cover. I didnt know I couldn't break in an engine with new headers. I chalk that up as a learning experience. But I still like the fit of the headers and the ease of installation. Nothing hits and everything is installed.

TinjunTribe Senior Member Join Date: May 2007 Posts: 129 Mergers and Consolidations -------------------------------------------------------------------------------- How many here have been through a merger/acquisition/buy out? One Co. buys another established or "growing" company that has good Brand Recognition. The new parent company doesn't always look for ways to make the product even better.....only more PROFITABLE. How can they make it more profitable....oh, maybe get rid of long time employees who are paid highly that know what the H3ll they are doing, replace them with lower paid inexperienced people, and new management that is from the new parent company..................maybe outsource the coating process if it used to be done in house....skip a step in production that seems "uneeded" in the eyes of the new manager.......lot of variables that can save a buck here or there. interesting that it coincides with Pertronix purchase. Guess we'll see how good their customer service is now too. "One time recoat".........so if they follow the same f'ed up process and it does it again you're SOL. Shame they even use that language, like they are doing you a favor......... Tinjun tribe has it nailed. He forgot to mention "Customer service" is also always farmed out now. |

those headders looks really nice good work that sucks the problems you are having, and right now, customer service in america is out the door, along with family values, etc... I've been tempted to get headders, and there is some good info here..... |

Everyone needs to go back and look at the pictures. This is not road stain or road kill on the headers, it is rust bleeding through the coating. I am lucky PY is willing to reach an agreement with me because Pertronix couls care less. Tribe has it correct, mergers and buyouts have led to a product we trusted ending up into the hands of a company that could care less and sees only money. They lost me and two of my buddies who are now purchasing Hedmans.

I bought mine last fall waiting on my 428 rebuild. no rust yet. All I rear before these were the best! I don't want to install if this will be a problem

I received a new set and they have the same issue of not being polished around the tubes where they meet at the collector. Will swap but I just don't have a lot of faith they won't rust.
I see Dougs is not available at major suppliers and PY as well as Summit have none in stock (570) or 570R). Wonder what is going on? Hmm, I like to speculate, maybe they (Pertonix) went to a cheaper coater to save a buck and now it came back to bite them in the arse? |

good luck with the new ones, let us know if they start rusting as well or not..
i think i'm going to take my old headers sand blast them and put some paint like por15's factory exhaust manifold grey on there and see how long that holds... either that or try the anti-seize on the headers trick (never done so i don't know how that holds either).

this is muscl car's from nastyz28.com trick.. i can't find the pictures right now but his headers look real good even after a couple of years. he lives in cali though with lots of sun so i don't know how it holds up in areas with more rain and worse weather.
anyway -> make sure tubes,flange and collector areas are clean of all paint and grease.now purchase a large bottle of anti-seize yes that's right anti-seize.with a cotton rag wipe the header completely with the coating probably 2 coats waiting 30 minutes between applications.next either using a blow torch or using your engines exh. heat after mounting on the heads .heat cycle them for 2 minutes or until they start to smoke.do this 3 times waiting 1/2 hour between heat cycles.once this has been done they will have the look of alumna-coated headers but for a cheaper price edit -> found a picture which somewhat shows the headers with the anti-seize coating, http://i114.photobucket.com/albums/n...ar/Picture.jpg

yeah i'm looking forward to giving it a try sometime and see how it holds up compared to painting headers.

Maybe you should have them re-coated locally before you install and elminate the chance of rusting out again. |

Ceramic coating is a dirty, hot, miserable job and epa regulations are causing Header mfg's to move production to Mexico. I'm not sure if this is the case with Doug's but I do know the coating operation is one of the reasons for the lack of stock.
