TOPIC:

Newbie about to undertake the restoring/customizing of a 1977 KZ1000. After too many PBRs and one and 1/2 viewings of Mad Max with my bro... I need to know where I can get a 4 into 2 megaphone exhaust for this bike. All I can seem to find are vance and hines and kerker 4 into 1 systems... I tried "search" but to no avail...

Here's one option:
ZeCross

Thinking Mac offered a 4>2?

Good Luck!

Systems from the 900 will work for the 1000?

Should fit just fine. Perhaps need to fashion a muffler hanger bracket (easy to do).

Will the stock exhaust from a 1980 Z1 fit?

There was no Z1 model sold after 1975. If you mean a 1980 KZ1000A4 (standard MKII engine), the system should fit but you may have to fab hanging brackets.

As far as a KZ900 system fitting a KZ1000, keep in mind that the flanges on a KZ900 system will be drilled for 6mm studs and the KZ1000 has 8mm studs meaning you may have to open up the holes to allow for the larger studs.

MAC makes a 4 into 2 that is inexpensive but they use turn-out mufflers which are not very nice looking, IMHO. I have an older set of black ceramic MAC 4 into 2 pipes on my bike with flared ends and I chose them for the look... I like it. The problem with MAC stuff is that it isn't all that great as far as fit and finish being at a lower price point. You have to use some muscle to bend the head pipes to make them fit and the flanges didn't have much material when drilling them out for the 8mm studs but I did get them on. One muffler went in all the way and one muffler just wouldn't go even though I beat it till I was tired. I ended up having to fabricate a piece of metal to go from the mount on the bike to the the hanger on the pipe. I couldn't get that muffler out of the head pipe down piece if I tried... it is JAMMED. Next 4 into 2, I will check out that system Patton showed from Z1E as it is probably better quality.

I think he means the Z1 Classic...which is essentially the same as all the KZ1000B (LTD) and KZ900B (LTD) series...minor differences but all very similar. And yeah, any of them will fit on the 1000 standards (you may have to fabricate a muffler holder).

Here is the Craigslist link atlanta.craigslist.org/mcy/1043283788.html

I have seen the turnouts from MAC, and I'm looking for the megaphone type. I also came across a rusty but complete set from a 1978 KZ1000 with no baffles that I can see in the pics... but for $130.00, I may go with these:)

keep looking on e-bay.. it took me almst 2 years to find my system 4 into 2 for my bike its a 1983 kz 1100 i found 1 on e bay that was in great shape for 280.00 + shipping
lok in the ebay stores and all over their and u might find 1..... i would go on every night and do a look around, as i could not find any online since i wanted the stock 1 that came with the bike .. ebay is your best friend

There is a black and chrome 900 in the gallery with the EXACT pipe youre looking for. I think its pig parts or pig bits.i saw the you tube video he has up...sounds nice i want one now as well.

z-1 900 section section 21 on the bottom row - black and chrome..pig parts. i tried to p.m. but im not able to on my limited computer..if anyone finds out what they are and where they can be had, could you post it...thanks, will
