im getting a garrett t3/t4 turbo and want a good exhaust system to go with it. suggestions? and i have seen where people get custom 3" piping ran all the way back and then put something like a kteller muffler or an apexi on there. not sure what i should look into? i was looking at an apexi n1 catback but im not sure? oh, i also just remembered about the greddy ti-c.

 

I would do custom 3" mandrel bent piping with magnaflow 3" resonator and muffler.
