For the time being, I'm actually pretty satisfied performance wise. Although if a good deal on headers or a nice nitrous kit comes along, I won't hesitate to take it
But now, I'm actually way more geared towards cosmetic for the moment. I'm looking for a v8 front bumper that I can add for a more aggressive look. I'm also on the look out for a GM ground effects kit for my car. At least the front splitter since it looks so good on lowered cars. Also, I might buy a heritage grille for the car. That should complete a nice menacing look.
I've also started to look into a sound system for the car.
