Lexus Owners Club Posted March 12, 2021 Share Posted March 12, 2021 Not sure personally but worth a punt as long as you have found lots of posts saying they will fit. What about the rest of the exhaust system coupling up to the headers? Quote Link to comment Share on other sites More sharing options...
