I recently had to remove the left rear muffler. (Repaired power antenna)
The Y pipe was rusted and needed replacement. It turns out that the Y
pipe is 2.5". The stainless steel mufflers are in great shape and I'd
like to keep them. They are not marked and I would guess about 12 years
old. Is there any way to figure out the manufacturer? Is it possible
that the 2.5" Borla would fit? Thanks in advance.
