Will I have any warranty problems when I lower(H&R) the car and change the exhaust(Magnaflow)
Ramie ?

 

It really seems to depend on the dealer.

Some dealers may:
1. cause trouble if they see a mod, or try and blame anything on the mod, related or not.
2. overlook unless there is a legitimate reason to blame the mod
3. install mods for you

No matter what they choose to do they should only be able to void parts of the warranty, ie.(suspension, electrical, drivetrain) not void the entire thing. I'm not 100% on this though.

Do some searching around here for your dealer and see what others are saying about them and their mod friendliness.

 

Not if your a bada$$ and strong arm them when they start to deny your claim...
