Tip - 120mm Piping - 75mm This catback system is one of the straightest available on the aftermarket, it's decently loud without a cat and really opens up the EJ series motors!

Best exhaust

switched from an ebay catback to the hks and wow what a tremendous difference. Perfect tone, quiet at idle and quite loud when you get on it. I have tomei headers, grimmspeed uppipe with a 40mm wastegate , cobb downpipe and this sounds perfect. No rasp or drone whatsoever.
