What type of Exhaust would you recommend me get with a dual set-up, I would like to get maybe the N1 from Apexi, but you guys have said its much better when in single exhaust with that system, and a full conversion from double to single, i'm not sure if I can afford that.

 

Turbo = single with good muffler.
N/A = full dual with 2 pre-silencers & 2 mufflers.
