Kostich Exhaust Logs Compared to stock.
Posted by: davemotohead ()
Date: June 11, 2016 09:25PM

These are really Bitchen, I am designing a exhaust system to go with them, super single and duels,The second and third ports have little kickers to divert the gases for better flow,thumbs up

They come in 2" and 2 1/4", These logs will fit the smaller head tubes as well as the 140, The 2" will fit under the lower shrouds with some trimming where the logs exit the shroud, the 2 1/4 will fit under the shroud With some trimming and Body work,You can get them with no flange welded on, or 2 bolt,3 bolt or the flanges just in the box to weld on yourself,

I DO NOT MAKE THESE! But I am going to make a complete exhaust system to go with these, If you would like a set Contact David Kostich: dmkostich@gmail.com : He ask that you include a Phone number in your email :

The set screw feature to adjust the pressure on the exhaust gasket is really cool.

Dave let me know when you finish the system. I will defiantly take a set. Will the duels have a balance cross over?

Ugh, one more must-have to add to my list. I'm anxious to see your finished product and here how they perform.

Hmmm. I guess this would be for the 140 engine only. It would be nice to have a set for a high performance single carb on each head engine.

Hi Dave, Wow, they look impressive!

Do they fit inside the lower shrouds, and if so, how much surgery needs to be done to the shrouds so the outlets can fit through? (It's a consideration for those of us who use our Corvair direct-air heaters).

It would also be neat to use a proper 2 into 1 merge collector for the big-single exhaust system you are designing. Here's a photo of mine, which I designed for stock 140 exhaust logs. I still have this system installed on my '66 Corvair.

I have a set of the smaller ones. I had him make mine without the outlet flanges as I am going to tig weld V band flanges on to mine. I have never liked those old 3 bolt gasketed flanges. With mine being used with a turbo it puts a lot of pressure on the gasket.

Great work Dave, as we have come to expect from you.

Is the log diameter too large to use with the stock lower thermostat shrouds and bellows for those of us in colder climates?

Are these Stainless Steel, or Mild Steel?

would they fit angled exhaust tubes, given the right flange?

Mr Kostich only offers them in steel. He will use heavier gauge pipe on logs destined for use on turbo cars. But when I inquired he had no desire to use or offer stainless.

No. These logs are designed for use with a stock exhaust packing/gasket.
All of the angled exhaust tubes I have seen are designed for a bolt on style header flange.
