The installation was a breeze. The multi-piece design of the Invidia is smart. I just had mine installed today. It only took about 2 hours or less, with bunch of chatting with relax pace at my buddy's garage. Even my car was lift on low-raise instead of two-post. The installation is just smooth. Needless to say, fitment is just superb.
However, I like to share a tip with anyone who is going to install their new Invidia exhaust system.
There is no need to remove your GT specs lower lateral bracing, there are lots of room. Make sure to buy yourself a new pair of gaskets for the section between the flex pipe and the cats and apply some exhaust cement on the cats flange to prevent any possible leakage. Invidia package does not provide that pair of gaskets. And this will happens to FX in area with a lot of rainy and snowy whether condition; the flange face of the cats will mostly be rusty when you took your old exhaust off, so new gaskets and some exhaust cement are highly recommended for highest installation quality.
My experience with exhaust is Awesome!!!
Nice deep tone, about 30% louder than stocks, but I love it. You will definitely love the sound when WOT

. For FX35, I did notice a bit of loss in low end torque for rpm below 2500 (not that noticeable unless you are a picky person like me

), but above that rpm the responses are faster. I am going for a dyno tune this week and should have that problem fixed up. :.smile:
