I have no problem with the Mac header. It's the Mac mufflers that are really cheap. They sound terrible and need a lot of jetting. The only issue to beware of is to make sure you use new crush gaskets at the head. Those steel flanges can bend and cause leaks (which leads to popping on deceleration). With new crush gaskets, it shouldn't be a problem.
I think a Kerker muffler on a Mac header would be good. In fact, that's exactly what I'm planning to do.
Oh, and I have Kerkers in several sizes. I plan on putting my Kerker K-series muffler on a Mac header. They are both 2.5".

Yes, you can get new baffles for a Kerker, but they are not cheap.

It's not hard to make one if have access to a welder. Or you could probably make the metal parts and have a muffler shop weld the pieces together. Fabbing the parts is what takes time.

Dennis Kirk sells pre-made, peforated tubes for making baffles. They have many many to choose from. Just search their site with "baffle".
Here's just one example:

I also have him on the lookout for me for some 83-84 GPz cams and some other stuff. /quote]
Not to jack your thread,just a quick note on the 83/84 GPZ cams. If you're putting them into a Z1/KZ style motor you'll need an electric tach.No tach drive gears on the GPZ cams.Ask me how I know this ....

what i did for my kerker was to pull out the old baffle and insert a muffler i got from auto zone for about 30 bucks. it sat in the cone about 1/2 inch diffrent so i just drilled another hole in the megaphone to attatch the kerker end cap.
How does it sound though? I like the look and SOUND of the kerker, so I dont want a kerker pipe that doesnt sound good. Does the baffle make a big difference on the sound?

hey jack. To be honest I think that the only J bike that has the tach gear on the cam is the CSR models, the LTD and J don't seem to have a gear. I should go take a look at my valve cover.
