Stainless Steel Natural Muffler Delete Tailpipes (85424) by Doug Thorley Headers®. Main Piping Diameter: 2.5". With Polished Exhaust Tips. If you're looking for that American muscle car sound from your Camaro without the price tag of a complete exhaust system then look no further. These rear muffler delete tailpipes do just that, remove the secondary mufflers from your Camaro and replace them with tailpipes that route the exhaust gaskets through beautifully polished 4" exhaust tips. This results in a wonderful street muscle sound without being obnoxious.
