I just bought my new 2007 tC standard. i was thinking of adding a Injen intake system and a Injen cat back exhaust. Will either one of these void my warranty? I know i need to ask my dealer but maybe one of you guys would know. and what the hell is the difference between a cat back and an axle-back?

For the true, unvarnished 'word.'

Short answer: Unless you fail to follow the preventivemaintenance required by you owner's manual, or the manufacturer of the vehicle can prove that the aftermarket product caused the failure, your warranty stands.

Even if a part of the warranty is knocked out by something you did, the rest of it stands.

 

Not searching voids your warranty..

 

OK, with that, I'll quietly lock this topic. :D
