Here's my question (plain & simple):
Is there any evidence, or any reported cases, that the installation of an aftermarket down pipe and/or intake has directly caused damage to any Subaru engine?
Don't get me wrong here. I am not asking if "driver" error caused damage. Just merely the addition of down pipe, intake, BOV, etc causing damage to the engine? Or addition of sway bars, strut bars, lower chassis brace, etc causing damage to the frame or suspension?
Granted, all these mods being installed CORRECTLY. Has it ever been proven that their addition has deliberately caused damage to the vehicle?
Just to be clear - I am referring to all of this UNDER NORMAL DAY TO DAY driving conditions. Not necessarily Auto X and the like.
Thanks.
