08 TL Type-S project car advice

What’s up guys,
so I’m pretty new to this but I have a 2008 Acura TL Type-S. I’ve been looking in to getting a truck but I love my car to much I dont want to get rid of it, I’d rather just turn it into a project car. My main goal is I’d love to throw a turbo in there, but it has 115k on it and I want to see what kind of shape the bottom end is in and how much it can handle. But for right now, I’m going to focus on sound and aesthetics. I would love to change up my exhaust as we can all agree that the stock exhaust is a little to quiet. I dont know exactly what I want to do yet, but what I do know is I dont want the car to sound like a ricer or anything like that. I want it to be a deep rich mean tone when I’m done with it. What would anyone reccomend?? Also I’d love to put some kind of intake in just to give it some kind of love. Other than that I dont really know what else there is to do, which is why I’m here. Any suggestions are welcome. No matter what I do whether it’s looks, sounds, or performance, I like things to be subtle, to seem close to stock but not stock, just the next level. Thanks everybody!!
