If anyone is planning on upgrading their 19+ exhaust, you will need a set of valve simulators. I just installed my DP and exhaust this past weekend and used simulators from AWE (several other companies sell the same ones). I paid $49 shipped!! These simulators are for Audi, BMW, MB, Ford RS.....anyway, after an extensive search, I found out the the valve motor on the Acura is the same as the others mentioned above. They clipped right in and has a sealed fit. No CEL light and I've put on 400 miles in two days. These are an alternative to the Fabspeed 's $300 set that they sell.
