All: I happened to be over at my car storage yesterday and so had a chance to check the length of a Sono 6X which has resided in my 300C trunk for many years. The body measured 34 1/8" long. Guess it could me safely rounded off to 34 inches. Interestingly, the specifications I have from Chrysler Engineering call out 35 inches as the length for the 300C muffler (Arvin #2192BW). Where did the inch go? Got lost between engineering and service, I guess! For Ron's question, yes, all aspects of the 300C and 300D standard equipment exhaust systems are identical. I am pretty sure that statement applies to the "C" and "D" convertibles as well. Hope this is of some help. Thanks, Marv, for the info on the source for these components. 300ly, Gil Cunningham In a message dated 7/23/2010 4:44:21 P.M.

The body of the 6-X is 34 inches and total length is 39 inches. The Sono 4-X body is 29 inches and total length is 33 1/2 inches. I have both Mopar Sono mufflers in my basement which I checked the measurements. We have the Sono 6-X on our original 1957 300C which will need replacing soon. We purchased our 300C in July 1958.

Based on the title of your email, I would assume so. But just want to verify.
