Congrats on the new ride! I have a Roto-fab cold air intake, Bo White ported TB, I'm installing long tube headers as soon as they come in (have shortys now from previous owner), and Solo Mach XL catback. Roto-fab's quality, appearance, and performance is second to none. They're really excellent and I have bought multiple cold air intakes from them for different vehicles.
Solo's catback makes a L99 with or without AFM (4 cylinder mode) sound awesome! It gives it a deep muscle car rumble while being 100% drone free! The best part IMO, is that when you're cruising around it is nice and docile, it is close to stock cruising in the cab. However, the moment you get on it the car screams!! I saw one of my neighbors on the highway the other day and at first he didn't realize it was me so he zipped off in his Mitsubishi Lancer Evo. Once he slowed back down I punched it so I could show off the Camaro. When we got back to the neighborhood and saw that I was turning into my house he stopped and said, "man that thing is LOUD!!" He loved the sound so much that he almost went and traded his Evo in for a V8 that afternoon!
One mod that is MUST for L99's is a ported throttle body. Bo White is the best for hand porting that I have seen and is incredibly reasonably priced. He is supposed to be taking work again soon and when he does, get on his list to get your TB ported, or get one from him that he has pre-ported. He uses GM cores so they are quality pieces and not just some piece of junk from any auto parts store. It really awakens the car and actually allows a L99 to do a burnout!
