1969 replacement sidepipe mufflers

[Dan M.]

My current covers are in excellent shape but I do need to replace my muffler/pipes. I'm asking for comments and views on should I go with a aluminized or SS system. I'd like to stay as close to stock as possible. I understand SS may offer more resistance to corossion/rusting.

The NCRS Judging Reference Manual has a Standard Deduction rule for SS parts used to replace factory original parts that weren't SS. The rule has several originality scoring deduction entries in a table depending on what specific part(s) is/are SS...

Don't know which to recommend since I never bought a aluminized or SS type of the 69 type side exhaust. I did buy original type replacements from GM when I had the system on my 70 many years ago. The original aluminized exhaust on my 85 Corvette is still on the car. The left muffler needs replacement because the outer shell has some cosmetic deteriation but no exhaust leaks through the inner metal. Keeping a car in a garage out of the rain and off salted roads will increase the life of exhaust systems a great deal. I liked my 69 style exhaust the best when with years of use there was just a shell of the muffler and my daily driver.
