I made a mistake in the year of these mufflers, turns out they are for a 1972 GTO. The # stamped in the mufflers is 86103757. The one picture shows that the finish came off one of the mufflers from sitting in box for so long. Sorry about the wrong info in the ad title, not trying to trick anyone, just my own stupidity not double checking #s.

Troy so they don't say Oldberg on them anywhere? Did you ever make out the date on them?

Lyn.

Don’t see a date or any other stamped markings other than what is in the picture.

Ok so these must of been made by a different manufacture than the original's on mine as mine are Oldberg and don't have the made in Canada on them? Would like to hear other's idea's as to who was the manufacture of these since they were made in Canada and what plant's would have used these?
Lyn.

Just wondering if you still had the mufflers?

Thanks Lyn.

Yup. Put one set on my car and still have one pair available. They are fairly quiet with a very slight rumble when RPM is high. Can text me at 13065378784 if you need any more info.
