newbie here
 

hey guys, i just bought the '09 GS350 awd and i would like to know what kind of upgrades would be preferred in it.i was gonna install the typhoon intake but the dealer told me it isnt a good idea since it could void the warranty while installing the catback exhaust is fine with them.what i woukld like to know is if you guys know any ways around it and preferrably any websites where i could find reasonably priced F rims. thanks in advance
