I've enjoyed reading these posts, I found all of the information very valuable. I originally just stopped in to compare k&n vs ram air. And got more than expected. I bought a Reband exhaust and when advised to pair it with a k&n system, I oops'd and put in an under seat stock replacement. My bad! Had a dyno tune done, to my regrettable distruction of my new chrome pipes. I only saw a gain of 10 hp(I was very disappointed). But when you don't have access to the real talent, I wish I could say you get what you pay for. It may have been more cost effective to cross the pond!
