Hello! I need some assistance. My boyfriend has a birthday coming up, and I want to get him heated seat inserts or a new exhaust system for his 2013 Subaru Impreza WRX hatchback. I need recommendations. He wants his Subaru to be louder and a little more aggressive, but heated seats are a win for both of us. Where's the best place to start shopping? I've looked at the Subaru parts store online, and it's a little difficult with my lack on knowledge on cars so I've come to the experts.
