get the exhaust, I've gone through a bunch on my S13 and it's by far the best system I've ever seen. The design is very form follows function. Even without the silencer, the car is considerably quiet until you get to higher RPMs and the straight-through resonator begins to be bypassed. IMO the slip fit connection is the best design for a low car, because there isn't that larger diameter connector to bolt together which always scrapes.
