4 into 4 exhaust

[slash360-2]

I have a 1981 750 custom with stock 4 to 4 exhaust.#2 and #4 have rust holes where head pipes meet mufflers.I like looks of the 4 megaphone mufflers but cant find them.Gonebiking listed a web site called mivv.com that may carry them but I couldn't them on that site.Mine are stamped #HM425A.Any help finding slip ons or full system would be appreciated.      Thanks Steve L.

Mivv carry the genuine four into four silencers. That where I got mine from via the agents in Queensalnd Australia and then delivered to my home in Perth, Western Australia. mivv can supply upui with other type of aftermarket exhausts. CLick on the mivv website, click on ENGLISH, then select your make of bike. From there the links will take you to the various makes and models of your bike ( Honda CB750 I assume ) There you can select either the standard four into four system or another type of exhaust if the 4 into 4 is not what you are after. The full system is on the site excluding the header pipes which can be made up. The part number for the 4 into 4 is: 79.96.062.44 mivv dont make after market megaphone type systems for our particular bike. I think you will have exteme difficulty in finding aftermarket slip ons as a 4 into 4 system due to the age of our Hondas
