Indeed your right. I was driving the car today and it really does feel like its lost a lot of lower end power. Theres definately a smoother ride, moving through the gears, the car doesn't thrash as violently as I remember it being and when boost kicks in, its definately not what it used to be (maybe I'm getting used to it?). Would this actually be the case or am I being too obsessive? I had a look at the cat I removed and from what I can tell, it may have actually been a hi flow cat (looks a lot larger anyway, bugger!). What would everyones thoughts be?
