    Maybe I'm missing something but the product link you provided is a fuel additive, not for engine oil.

Size:  77.5 KBI just did a baseline dyno prior to headers.
    Realised that CVTs are difficult to dyno. I can only get bhp but not torque numbers.
    The car can't stay in one gear to give a nice ramping rpm to redline but instead it goes to redline immediately and stays there as speed builds up.

    One more thing we discovered is that the abs light has to come on for the car to accelerate to Full speed. Otherwise the car is limited to 80kmh on the dyno at redline.
    It's weird that my version of the Attrage has no traction control but it seems like the car is behaving as if it has traction control.

    Last thing is that no one thus far mentioned anything about the headers being longer than the stock headers. I had a hard time replacing them. Had to cut the existing exhaust and re weld to make them shorter. I am not sure if this applies only to Attrage and not the mirage.

    In addition, how do you guys get the stock headers out from underneath? Was there any additional components that needs to be removed? I had to disconnect the drive shaft on the inboard side to make space for the headers to come out. Was a mess of cvt fluid to say the least.

    Please note that Above graph is before headers but not with stock exhaust.
    I removed the 1 cat and have a hks universal muffler followed by a Vibrant Ultra Quiet resonator.

    The cats are removed but the 2 oxygen sensors are still there thus no engine check light and does not go into limp mode.

    I was looking at the photos of the headers on the first page and I noticed that on the mirage the first cat is bolted on and removable.
    On the Attrage it's one piece and welded together thus making its overall length shorter than that of the mirage. That explains why the headers were too Long for the Attrage. In addition it also explains why it can't be removed from underneath without removing other parts for access due to its one piece design.
