I'm new to forums. I just bought a 2019 Hyundai Elantra sport back in March. Figure I join this forum so I can BS with my fellow Hyundai lovers. So far I've put two 10s in the trunk, limo tint, and order the SXTH Cold air intake. Now I'm bout to order the Axel back exhaust. What other performance parts can I get without voiding the warranty?
