Ok I need some help, I want to purchase a new exhaust collector that houses the butterfly that goes to the heatriser for my ‘27 Buick Standard Model 27.


i know I saw this as a new piece available on a website somewhere and can’t find it again for the life of me!


Anyone know where to find one?

    What's wrong with the heat valve that you have?  What you should do with that one, or if you find a replacement, is to remove the butterfly itself.     Hugh

I have an exhaust leak at the outside point where then pivot rod gets thru the butterfly.


i am definitely going to do what you did and block off that two butterfly flies, at the collector and the heat riser, soon as I may just spot weld that point where the exhaust leak is and grind it off so it looks smooth.


Just figured if I could pick up a new collector I’d be nice to just bolt it in now.
