welcome to the site. i've seen your car on NCTuners. I'm Green_Machine still trying to sell my car lol

 

Welcome, get a JWT popcharger and a Motordyne plenum spacer while you're getting the exhaust and it will make your car sound even better, .

 

does the plenum void the warranty on the motor? i dont know if the intake does or not but that can be changed before going to the dealership for anything haha. and green machine good luck with your sale, i ended up selling my M3 in like a week.
