exhaust tips.

Then thats what you should run.....you have a good runing car your happy with, so there should be no debate as far as your concerned. But, facts are facts:
Direct injection has more advantages than just the cooling. That is a minor advantage. There is still detonation or we would not see it in logging these cars, but it allows higher CR with LESS detonation as the fuel is introduced in the final 2030% of the compression stroke so it is in the combustion chamber for a fraction of the time a traditonal carburated or port injection system that draws in the fuel air mixture on the intake stroke so it greatly reduces the incidence of detonation, but it is still there most definately. I'm not here to convince you of anything as you have shown yours is just how you want it. My contributions are for those that want to learn more and have the car run the best it can...and premium or regular has no effect on the exhaust tips, that is how rich or lean the engine runs and how effective the cats are.
