DetailsLexus RCF Rear Silencers - dummy rear silencers for a vastly improved sound with 4 large oval polished tail trims. Our customer's comments are: "The Lexus RCF sounds brilliant! It Just what I was looking for the low V8 rumble at slower speeds and at low revs. And when I put it into Sports + mode it's a completely a different animal and sounds crazy."
