350z HR -  
  
scorpion exhaust - pros , cheap / very subtle sound but better than standard , no drone . Cons , pretty poor build quality and fitment  
  
Scorpion + berk HFCs ...... Louder than the above , a lot of rasp ( I didn't like it ) no drone  
  
Invidia + berfs HFCs ..... The most well made , quality exhaust I've owned , The v6 came alive , epic sound on full throttle , stlight drone  
  
Miltek + motordyne art pipes ...... Art pipes are absolutely quality , worth the money . So quite paired with the miltek . No drone ..... Bit too quite  
  
Art pipes + ark grip ....... Don't know, but looking into getting one
