CB 450K Muffler question.

[Klubfoot]

Hello everyone,

my name is Steve and I´m new around here. Great place! ;D
Which mufflers will fit my ´72 CB 450 K5 with the stock down pipes?
Of course I searched the forum already but I´m still not sure.
I´m looking for a good, deep sound but not too loud. Maybe with removable baffles.
Any ideas!
Thanks alot!

Stephan

Hey Steve,
any muffler with a 1.5 inch inlet will work.
You may have to rejet the carbs if you remove the baffles.

As he says, anything that will mate up to your head pipes will work, though a quick trip to an exhaust shop can help hang just about any muffler off your pipes.

As for your sound preferences, you'll want to look for mufflers with a very large internal volume, thus a lower resonant value.
Basically the more internal space the muffler has the better job it'll do cutting the sound without choking the flow.

Thank you both!
