I want to get an exhaust and shocks/springs setup. A place near me can get both a cat-back exhaust and sport springs from AAvantGarde. Anyone ever use any of these? And I wonder how their springs stack up against Eibach, H&R, B&G (from TAP), or Neuspeed? And how does their exhaust compare to HKS's one????<p>As for shocks, it looks like I will go with KONI.
