Yoshimura Exhaust Low Volume Insert
Sorry this may be a dumb question, but I just purchased this exhaust from Ebay:
Can anyone please let me know how to tell if the low volume insert is in it? I removed the rubber circle and do not see a screw inside (just a little metal plug that covers a hole into the exhaust), and I look at other exhausts and they appear to have a ring inside the tip that I do not see on mine.
Do you guys think the insert is in it?
