I doubt you will get any more power from a one piece over a o2 housing and extended DP.. cool concept though

It hows no 90 degree bends kept them as small as possiable to make hp gains over the other after o2 housings, down pipes and test pipes.

No it does not throw a check engine light

You sure that the placement of the secondary o2 is good? theres a good chance that stuff will settle inside it when things cool down.

i dont see how it wouldn't throw a CEL, there is no cat so eventually the 02 sensor will read too much flow without any type of cat being there. if it hasn't thrown a code yet, it inevitably will. nice idea though for those who won't get bothered by a light on the dash. but i would be more worried that there is no flex pipe. having everything unable to move like that is asking for something to crack

No primary cat means a cel, cel means the car is leaning out too much. Everyone that makes o2 housing recomends getting a tune or you might have engine problems later on.

How about some dyno #'s

If you look at the second u2 bung it is almost spaced out two more inch then the first on so that it gives it the same signal as if there was a cat. We also have one with resonators and flex pipes

Just because its "spaced" out like the cat was there doesnt mean anything. Their is still no catalyst to burn off excess hydrocarbons. Period. Looks decent minus the part where there is no flex pipe.

When We where done with the car we put it to the test. The customer and us took the car drifting all night and never got a check engine light.

Most CEL take several drive cycles to become a hard fault and throw the light. Give it 10 cycles with 20 or so miles each cycle and im sure youll get the glowing demon.
