Whenever I say something about having straight pipes, someone always mentions something about back pressure and not having enough low end torque. WIth that in mind, whenever someone mentions something about getting a catback, people always denounce it as being stupid and useless compared to an O/R X pipe.
Now which restricts more? The 4 cats or the 2 mufflers? I mean if you got a O/R X wouldn't you lose more backpressure than on straight pipes or resonators?
