Ahh... It will not void the car's warranty, but it may void the exhaust warranty, unless the shop installs it. if you install it yourself, they may dispute the exhaust warranty. it's typical toyota BS. Read those papers you signed when you bought the car.
Most toyota service people will be cool with it if it's a TRD
, but if the unit goes, they may have you spring for the expense because it was an "Aftermarket part" so they'll replace it with a factory exhaust (covered under warranty). You gotta pay for a new TRD
exhaust if you want TRD
However, if you have the shop do the install, the TRD
unit is covered under the factory exhaust warranty, and if it goes, it is replaced under the exhaust warranty with a new TRD
cat back, instead of a factory unit; which is a good thing, considering the # of TRD
problems reported lately (apparently, the mufflers and welds are blowing out on a lot of them)
In general, most dealerships don't care what exhaust you have, so long as it's installed properly. but unless the dealer installs the TRD
part from the get-go, they won't replace it with anything but a factory exhaust.
The lesson here: Buy a good, all-stainless exhaust instead. TRD
is nice, but only the tip is stainless. the rest is all mild steel. this is to keep the weight down (stainless is heavier).
