Hi Marv, The original 300C and 300D Hardtop mufflers were "MoPar Sono 6X" which are 35" in length. Your Sono 4X are a little shorter than the Sono 6X. Wayne Graefen's 1957 300C Handbook, Sixth Edition, under Chassis, page 4 has a Section on Exhaust Systems. John Chesnutt, Portland, OR, 300C - Owned since July 19, 1958. -----Original Message----- From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of mjraguse@xxxxxxx Sent: Wednesday, July 01, 2009 6:32 PM To: Chrysler300@xxxxxxxxxxxxxxx Subject: [Chrysler300] 57 and 58 300 exhaust system sources I need to procure an exhaust system for my D coupe. I have the Sono 4x mufflers but need exhaust and tail pipes. Have any members purchased these pipes recently? Have any ordered them from Waldrun? I can go to a custom shop but think if I can get them formed to the original bending card and then take them to a shop for minor fitting I will be much further ahead.
