I am intersted in giving my Lexus IS 250 a little more sound and power. I am interested in getting an intake and an exhaust system... Do these happen to void the warranty? I know that headers do. Thanks

 

any aftermarket can void the warranty if the dealer can provide proof that the item caused whatever part to malfunction

 

Those two items that you are considering are so common that Im pretty sure most dealerships would not try to prove they were the cause of any problems. That being said, before you start dumping money into "performance" mods you might want to search around here a bit more. Both of those "upgrades" really dont add anything to performance, but rather really only add to sound. Lexus did a good job from the start of tuning everything to it max potential as far as airflow goes.

 

Listen to ben, he knows the 250 *i think he sleeps with his car at nite in a very unappropriate manner, wink wink nudge nudge

 

lol haha, ya it seems like he has spent a lot of time upgrading it with small mods
