IS300 Running Costs- 1 Year On
From auto anything "An increase in fuel economy is often experienced after installing a cat back exhaust system. This is the result of the engine not have to work as hard pushing exhaust gases through the piping. This reduces the total amount of load on the engine, causing higher efficiency and MPG. This increase in fuel economy typically occurs when traveling at freeway speeds, but can sometimes be noticed when driving in the city as well. " can't imagine it's going to be a dramatic increase mind.
But you are driving Hiccup carefully and slowly so that's probably a correct reading lol.
did sam put a frog spell potion under the accelerator so if the peddle pushes down to far it breaks the glass container.
more than likely.
