I have no problem with you, but there is no chance in hell that is putting out 280, especially not at the wheels. You should probably be happy if its doing 180 after some work.My 4 cylinder Grand Am is making around 280Hp on all motor right now, still a work in progress, but I'm wanting to see what I can get it up to. I have an SLP exhaust system, and it's pretty loud once I hit the throttle. Some may think I sound like a ricer. I don't mind some imports, but people who put bolt-ons just to make SOME power and think they have great amounts of horsepower, is just disgusting.
