I just started modifying my 08 G37S 5AT, sports,premium/ I just changed my intake to injen CAI. I'm thinking to move on to next step.. what would you guys do first? I'm asking what would you do if you were me..

1. change exhaust (HKS Hi power cat back)
2. change suspension (HKS Hipermax III Coilover Kit)

I'd appreciate yall opinions

I would get an exhaust (Invidia Gemini) and Tanabe Sustec coils for the same price as either one of those...

 

Get coilovers.
