Hey i was just wondering if anyone new which modifications are illegal in new jersey. cus i don't wanna modify my car then get fined or have the modifications removed when i get my car inspected.

Also what are some basic beginner modifications that i can start with if im lookin for more horsepower?

If anyone can help me out, i would appreciate it. Thanks

you prolly want to check with the local authorities as well as the BMV.
