Yeah I was trying to figure out what 1000 words that picture was trying to say

 

Not sure I totally understand your post but if you mean why one is so much less than the other it's pretty simple. Some are mass produced at $.30 hr with lower quality stainless at almost production line type manufacturing. Others are using higher quality stainless and are made one at a time in lower quantities, with labor costing way more and warranty costs figured in as well. You can buy a ebay manifold for less than it costs me just in buying mandrel bent sched10 tubing.

~S~

 

After pricing everything out going with a "kit" is often no more expensive than putting quality components together yourself.
As said different people value differently, but if your going to go through the time and expense of a single turbo I would reccomend you not skimp on one of the most important pieces. I would also think about the ease of warranty if the worst does happen...

 

Trying to get a warranty claim processed when the company is in California and you are in Eastern Canada must really not be easy.

I am still debating waiting with the Canadian dollar in shambles right now I don't have too much of a choice.

Zero R .What effects if any do non-tubular tubing ala HKS SS manifold have on exhaust flow, response and power? Also what is the difference between the response of a long runner versus shorty manifold?

 

I try to stay away from ss manifolds but if the power levels are low then I will go for one.I have a greddy t4 laying arround some where from one of my builds.Greddy nothing but good stuff.used it with a Trust t78-33d and a 3" downpipe.sweet man.
