I have a stock exhaust on a 06 g35 5at sedan.

I noticed the coupes are lucky to have the ful hks hi-power exhaust SYSTEM.

The sedans only have the hks sport rear section - and single also - not dual outlets like the stock.

Are there any dual outlet HKS exhausts for sedan owners?

I dont want stillen for drone and I heard borla is not much louder than stock. Am weary about fujitsubo or tanabe..

 

fujitsubo and tanabe have a much longer racing history than both stillen and borla. I would trust the design of both of those more than the stillen or borla ones.
