is the Apexi N1 Dual tip cat-back system a good setup for the fc3s? i just purchased it and its on the way so i better hope so... what do you guys prefer? i was going for the hks titanium racing exhaust but thats a little pricey.$$

 

It's a good setup for the FC3S if that's what you need.

NA, Turbo, Nitrous? Modified? What modifications?
These questions determine what exhaust system is perfered.

I can't say if the Apexi for the HKS system is better becuase I do not know which engine or what setup you are putting it on.
