The baffle can be used with most of the "Pro Pipe" line of exhaust from Vance & Hines. (Ask them about the "Quiet Baffle" part number for your make & model--it'll probably be 21906.)

I've had the baffle installed for the last ~21,000 miles. I replaced the exhaust and am trying to recoupe some of the expense.

$75 OBO + shipping (from zip code 73150)

End cap has the same use on it and is also available.
