Philippine's GT 86 aftermarket stuff
 

And so many 86-brz owners upgrade their exhaust, headers and stuff. I wonder how will this affect Toyota's warranty ?

I hope someone can share their thinking and experienced because i'm currently in envy.

Thanks in advance

if something goes wrong and they find that it was because of the aftermarket parts you've installed then they wont cover the warranty

but if you installed an intake or exhaust and something goes wrong with your suspension or electrical, then they should still cover that

The chance of something going wrong with simple bolt on parts is slim.
Just make sure you have it installed by someone who knows what he is doing.
If you are worried don't do it. Worst case, if something goes wrong, you can have the car returned to stock and try to claim warranty.

@pcuerpo @andrewFT86 Thank you !
