Bob, please use the search function. The topic of BOV is probably the most discussed topic on this site. The TXS RFL is a popular one I suppose, but keep in mind that BOV's actually hurt performance and there is a chance of actually melting the uppipe cat due to the nature of the 100% atmospheric BOV.
Welcome to the website, but I suggest you look into mods that actually increase performance and not hurt it. Along with the BOV, mods like the Cold Air Intake and Turbo Timer are unecessary for our cars at near-stock levels.
However, it's your car and you decide what you want to do with it. Please search "BOV" and read the "engine performance faq" in the engine performance section.
