You can install any part you want and it will not void warranty. Magnussen and Moss act puts the burden of prof on the dealer to show what you did damaged the car. So you could install larger turbo's, muffler and so on.
With that said it comes down how much are you ready to fight a particular dealer if a issue did arise.
Now back on topic. Is ER the consensus it is the best charge pipe when using the stock diverter valve? Or should I change to a BOV?
