Re: [Chrysler300] '58 FI exhaust piping question

[Ray Jones <hurst300@xxxxxxxxxx>]

An answer from Wayne Greafen:

At least on the 1958 Chrysler 300D EFI cars the primary exhaust pipe (and rest of the system) is NOT the same as the standard 300 or New Yorker.   The EFI option coded cars included, as part of the package, the low restriction exhaust manifolds and the 2.5" pipes all the way out on the hardtops.   These would not have been employed on a EFI convertible where the 2.5" system does not have adequate clearance in the X-member frame.   
 
What were the low restriction manifolds?    They were the truck style 4-bolt flange manifolds that the factory had madified in 1957 to fit the new torsion bar chassis to gain clearance at the steering box and at the upper right control arm.    I reproduced these manifolds for the '57-58 392s.
 
I do not know if there was any change in DeSoto or Dodge EFI exhaust manifolding or exhaust system but do not believe so.

Subject: CURIOSITY QUESTION ON FI 1958 CARS

HELLO MEMBERS, and a happy Memorial Day Weekend

Concerning the parts book and the 58 FUEL INJECTED
cars........................

WHY would the FI cars have a separate P/N for the primary exhaust pipe from
the exhaust manifolds?????????????????????????

The LENGTH is the same for the CARBURETED cars The diameter must be the same
because the secondary exhaust pipes are all the same.

ANY IDEAS
