Topic: CB750K Exhaust

[youn6372]

Well this is my first post here and I just bought a 1973 CB750K.  I have been a sportbike (GSXR1300, ZX1100) guy my whole life and finally come to my senses! 

Im sure this subject has been addressed but I am in the process of buying a new 4 into 1 system for the bike and I would like some opinions/suggestions/comparisons concerning the following:  MAC, Kerker, or YAMIYA.  Thanks guys!

welcome to the forum. First thing post some pics of your bike. Here is a picture of my 750K6 with a Mac 4 to 1 pipe. Im the 3rd owner and one of the PO's put this system on it. I want to get the Honda original 4 into 4 pipes back on it. There still can be ordered from Honda, but they aren't cheap. The Mac system is alright and sounds pretty good and is a whole lot cheaper than the factory pipes, but I just don't like one side of  the bike being bare without a pipe. I think a new set of Mac pipes like these run about $400.00 now and a lot less than the $1200.00 for the orignal 4 in to 4.

It kinda depends on how much you want to spend, and what look you're going for, and whether or not you're willing to re jet.  If you've got a 4-4, you'll have to re jet for a 4-1, and vise versa.
