i am installing a o/r h pipe and a magnapack cat-back tuesday and while i am at it i am going to have the guy adjust the timing for me, i was thinking about bumping it up between the stock timing (10 degrees) and 14 degrees because i dont want to have to put 93 octane in my car (because of money). so i guess my queston is what kind of performance am i going to get from doing this? acceleration, more hp, or what? i have just heard it is a simple way to get more performace.
