Well, my dad has told me that I am going to need a new clutch soon, but it's not too bad right now, I guess I will have to wait until it gets worse!
I already do have the K&N filter in it, I have an Apex-i N1 exhaust(not sure if it's 2.5" or 3" previous owner put it on), by the way, can you get pillars that you can have like only a single pod and eventually add another pod to it?
