Copper exhaust donuts

If I'm correct those springs are just from industrial ceilings.


I had the springs made....cost alot of $$$ as spring companies dont like small batches and numerous trys to get the right compression....

so theres your answer

Hey, where is my set on copper donuts. I guess I will have to make some on the lathe myself!!!
 
Just finished installing my new copper exhaust donuts. My old ones have just under a 1000 miles on them,(replaced at the start of last season) not much left of them. Besides a boost leak i would say a fire hazard as well. Thanks a gain Thistle, much appreciated

WOW those ones were bad!!

Made a huge bunch sept first....there all gone. Thought those would last threw the season but I was way wrong. Must be more yammies out there than I thought:face-icon-small-ton

So I made more and have em in stock and ready to ship.

Thanks guys
 
Thistle, do you know if OFT had these IN STOCK? I ordered them from OFT last sunday and thought I would of had them tue-wed as they are only one state away. Tried calling both the OFT guys yesterday and no answer. Sure hope they show up tomorrow so I can continue. two of the four stockers were completely gone. Thanks Eric
 
Be forewarned that the new coppers donuts smoke when you first spark the sled up. I thought I had an oil leak under the tank but, turned out to be the copper "offgassing"! Great product Thistledoo! Sherm
 
Still getting pms and such on these....have some more ready to ship

Also have some dealers in western canada if need be....pm me for details

Thanks Brendon
 
I have 1 used set, taking offers. They work great just using a different header system now.
 
Made more. Who hasn't got these in there rear mount set up. IMO they are a must and can save a deep pow day where your sled won't run tip top. Pm me for orders.
 
Neil from boost it now has these on the shelf for anyone getting work done or lives in that area

Thanks Brendon
