Just curious, been reading so many threads that contradict each other that I thought I would post the question directly. SO:

Does an intake kit (K&N) and cat back exhaust (looking at gibson) show any improvement in power, torque, an/or MPG??!?!?!? Or are they both a cool add on that has no positive benifits?

 

I'll let you know when mine show up. Ordered the Volant intake and Magnaflow exhaust . Hope to see a benifit in milage or performance.
