i have a 2002 tracker with 60,000km on it. Has the 2.0l with automatic trans. After a lift and putting 235/75/15 tires and a roof rack on it struggles on the highway. I was wondering if anyone has removed the rear cat and if it made any hp gains, was thinking of doing that and installing cold air intake to hopefully get a couple horsepower, any other ideas to gain hp would be appreciated. I realize i won't gain much without an engine swap but just looking to gain enough to cruise on hi way. I changed plugs a couple thousand km ago, would changing out coils benefit any or is there no point in doing so until there are signs of them failing.
