Need opinion on turbo piping.
This is my first turbo set up and I'm still new, I just bought a T25/T28 turbo and was wondering if this is a good set of pipes for my kit.

And would this be too much for my set up.
EK with GSR swap, apex n1 exhuast?
Any opinion on Blox products?

That manifold is for a T3 footprint. No T25/T28 will fit it. If you are using a DSM T25 (TD05, etc), then you can use the Honda Civic HF manifold with adapter plate. Otherwise, I say just use a log manifold. It has been shown from dyno tests, that log manifolds actually spool sooner than "equal length" manifolds, but quickly lose efficiency at medium boost.
However, the T25 will be losing efficiency anyway at high flow, so you won't be giving up much.
For the piping, what tools do you have? Can you weld mild steel? Weld aluminum? Braze aluminum?
With a $100.00 110v flux-core MIG welder and a hacksaw, anybody can learn to fabricate charge pipes and exhaust themselves. I would stay away from Ebay auctions for piping, as you can get it much cheaper from elsewhere. I buy mandrel bent J-pipes (180°) from summit racing; it's the least expensive that I have found. Then you just cut the angles you want, weld, grind and paint.
If you don't have a welder, get one. They pay for themselves the first time you make a mandrel exhaust or a set of pipes.
Optionally, anyone can make aluminum pipes as well. Get some "alumaloy" or "alumaweld", or just buy generic zinc brazing sticks with flux. (The brand name kits "tin" the aluminum with flux-embedded brushes) Basically with a propane torch, you can join aluminum piping just like soldering. Believe it or not, for the relatively low-pressures and low-loads the pipes have to endure, brazing works just as well as expensive TIG welding.
If you want to go that route you can usually buy aluminum bends dirt cheap from HVAC suppliers, though you have to pay more if you want centerline radii of less than 6".
Now, if the pipes are going to go past 20 PSI, or are load-bearing members, TIG is required.
