Default Mods vs Warranty - Setting the record str8

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.

First of all, wrong forum.

But, to address your questions:

The addition of aftermarket parts changes the design and operating parameters of the engine. Same thing goes for suspension parts, electrical accessories, etc.

Even if they are installed correctly (and the ECU retuned where necessary), those modifications mean the car is no longer within factory specifications. Therefore, the factory does not have to honor the warranty in case of failure. Honestly, you can't blame them for that. They have no control over the quality or performance of a modified vehicle, and can always use the "outside of factory parameter" reasoning for denial of a claim. If you are at all concerned with warranty coverage, leave things stock.
Now, may I pose a question? If the vehicle is to be driven under normal day to day driving conditions, what valid reasoning is there to modify it? The car, as delivered from the factory, is designed for that, and is quite capable. Other than personal desire, there is no reason for it. If you are building a dedicated track car, that is a different scenario, but then you aren't concerned with warranty issues anyway.

Wrong forum entirely.

It's nearly IMPOSSIBLE to install a downpipe incorrectly. The problem comes in the changes that come with the downpipe, aka you need a tune. This is where the error can come into play, and potentially destroy the motor. (Along with what SpamBot said)

And I have no idea why if you have a serious question you say "Str8" instead of STRAIGHT.

If you're at all worried about the warranty, don't mod.

Car companies dump tons of money into their Research and Development department to develop and engineer EVERY single component that goes into a car. Everything they put in that car from a simple bolt to the engine to the chassis is backed up with years of testing and most importantly quality control. All those parts have to go through a vigorous testing to ensure that it can withstand certain degree of usage not only as a part itself, but as a whole when they put all the pieces together. So when you put aftermarket parts on, you are simple throwing all the quality control they put in designing the car. That's why some aftermarket companies will have their own separate warranty. The auto industry has standards that everyone must meet in order for the car to go into production. There are exceptions like Subaru's SPT, Toyota TRD, Nissan NISMO.

A couple of things:

1. You misunderstand the way warranties work. They do not have to prove anything. They just have to make a reasonable association between the part you changed and the part that failed.

2. How could anyone prove whether a downpipe was or was not a major contributor to engine damage? They might have an opinion, but I doubt that anyone can prove it either way.

If the engine is damaged and there is an aftermarket part that *could* have caused the issue. Claim Denied.

When in warranty, don't mod the engine (or other stuff covered by the warranty). Unless of course you are willing to pay out of pocket.

There are several long threads that discuss setting the record str8 already.

A warranty is not voided on a car, its denied for certain warranty claims if its not oem, or a non oem part impacts it.
