Will the Perrin front pipe void my warranty??
 

I am just curious. I should ask before i buy the damn thing.

No, a single aftermarket mod does not "void" your warranty.

If something breaks on your car and the dealer/manufacturer can blame it on your aftermarket mod, they are certainly within their right to reject any warranty claim on damages related to the mod. They can't decide to not cover your headlights for something like an exhaust mod though.

it really depends on dealer but might give you hard time.

Definitely try to find a mod friendly dealer.

Anything changed that was not done by toyota with their "markup" will void warranty.
