Has anyone got the answer or workaround for getting a dual set of stacks to smoke equally. The question seems stupid but I know of any number of stack owners that have said they have this problem. It seems that the majority of the smoke comes out of the driver's side stack.

 

someof the guys that have made their own boxes put a piece of angle iron in to act as a divider. some say it helped whil others weren't convinced.

welcome to the site BTW.

 

That would depend on your "Y" pipe and whether it is a true "Y". I dont have any issues with mine shooting more smoke out of one side than the other.

 

The exhaust will take the path of least resistance. probably the "Y" pipe that splits it is more inline towards that drivers side where the flow doesn't have to change direction much to flow that direction.
Did i explain that as badly as i think i did.

 

If the Y is not directly in line with the pipe coming from the front, that will happen. If your Y is in the center that will happen unless you turn the 90 to the side, then install a 90 to face forward.

 

Well I've been asked this question alot lately...and I've asked around to a few places, and talked with people who has been doing this for a very long time. Even the big trucks, Pete's, Macks, Internationals, do this. And the only thing that I have heard that makes the most sense to me has been the temperature of the exhaust flowing to the driver side of the truck is cooler (which cooler exhaust smokes more I'm told) than the passanger side. Even with a splitter plate in the y-pipe, the driver side will still smoke first, and appear to smoke more than the other side. I'd like to get a thermal reading from a set of stacks once just to see if this therory is true. I can see how it would be cooler, since it is traveling a greater distance than the passanger side.

 

Thanks for all of the answers. All of your answer makes sense, especially when you take into consideration the laws of physics which state that heat will go to cold and that the path of least resistance is always preferable to any other.
