will a 74-77 911 Leistritz Muffler fit a 911SC with the pre 1974 heat exchangers

[82SC]

just wondering if the outlet will fit the valence....

I think it will. Up to 1974. 1975-77 and later, you will have to plug the port on the muffler...

First of all, the equal-length, tuned heat exchangers were used thru the end of 1974 USA models, and ALL of the MFI 2.7 and 3.0 engines worldwide, into early 1976 production for South Africa and Australia!

Any dual inlet muffler will fit the 'early' heat exchangers, but may require valence modifications!
