Finally picked up my 2011 G37x coupe. I wanted a G since 06 when the 35's were killing it. Got this bad boy for 23k with 35k on it. What are some visual upgrades that don't break the bank I should start with?

 

Moved here for a proper intro.
Welcome to the site Freezy, congrats on your new X coupe. As far as cheap visual mods, window tint comes to mind, an axle back exhaust such as the TopSpeed for a deeper tone and nice exhaust tips would be an affordable upgrade. Down the road some wheels perhaps and go from there.
Enjoy the site and your new ride

 

Congrats!! I recently got my 08 g37 coupe and man it brought back feelings I haven't felt since I first drove my first car!

 

I would also say maybe window tint if your windows aren't already tinted. First mod I am starting with is lowering my car. I went with coilovers right away which costed me 640.00 for tein coilovers, and now I need a camber kit which may cost another 500.00 from what I've seen, which I was not expecting. So if you go with lowering, I'd say start with springs since it is less costly. unless you're ready to drop about 1k

 

Windows came tinted I am a show no go type of car guy. (Tooooo many tickets back in the day) I want to just have my car looking nice rims are about a year away because I dont want to rush and buy some cheap ones. My exhaust does not sound the loudest what is a way to make my car sound louder?

 

These are pretty common and deepen the exhaust note, they have two versions but the beveled/rolled tip setup in this link is the one that looks much better, the angle cut straight wall tips look poor. They're out of stock until June though
