I should check my cat, have never looked at it. I have 123,000 km's on it (76,000 miles). I'm also not one of those people that likes to drive with their foot to the floor. On the highway I apply the law of dimishing returns with regards to how far I push the gas pedal.... I find the "sweet spot" so to speak and don't push it any harder. I would agree that these things require a lot of rev's when going against a strong head wind or up a hill of any kind. I can only hope my cat is clogged because then I'll have a reason as to why it feels kind of guttless. Otherwise, I keep pretty good care of it (synthetic oil, fancy bosh plugs, regular air filter changes etc).
