Okay....yes it was 250, but I waited close to 14-weeks for the exhaust I considered to be the best, so getting it installed by a shop that sold me the car, that installed it perfect, clearance at every point, was worth every penny......and I could afford it.

Intake won't void it either

bolt on mods wont void the warranty unless they can prove that the specific modification caused the damage.....

For example you install an oil cooler, a fitting comes loose, draining all the oil while your on the highway, engine is toast, you are liable.

If you are really scared, then when you have an issue, just swap your stock part back on before you visit the dealer.
