I literally just installed these yesterday. I had HPS tubes and HKS drop in filters. The installation was really easy and the instructions are really good (although not really needed). At wide open throttle, the engine is definitely a lot louder. I think whoever posted here saying that it is barely louder than stock is deaf or something. I think it is well worth the price. Throttle response is increased as well (which I was looking for).
By the way, there is a thread about having some issues with the tubes K&N provided that connects to the engine but I had no problems at all. As for next modification, I will be installing hi flow cats.
