Good news for owners and builders of classic Japanese superbikes from the 1970s and 80s. Harris Works Collection have reintroduced the exhaust systems for those bikes, which were originally developed to add ground clearance.
To finish them in black chrome, the chemical compounds used in plating are altered. That’s apparently not an easy process, so all the Harris Works Collection exhausts are made and finished in the same UK production plant to keep quality high.

The Harris Works Collection Black Chrome Systems are currently available to fit the Kawasaki Z650, Z900, Z1000, GPZ1100 and Suzuki GS1000. The 4-into-1 systems can restrict direct access to filters and drain plugs on some models, but centre and side stands aren’t affected. They cost £417.60 with a road legal baffle fitted, with race baffles in a bare finish available for £40.68. Call 01926-832345
Find more motorcycle products here. And you can also find new and secondhand Harris exhausts for sale via eBay.
So they are still mild steel? Bloody things were rusty before you got them unwrapped, not everything was good about the old days.
Brilliant news………
What about good old Chrome? GS850.

Do you make a chrome system for a 1980 KZ500, Regards Richard
Looking for a exhaust for a ZR1100 Zephyr
I’ve got the same Harris exhaust on a kawasaki z900a4 but with no baffle. Do you sell the road legal baffles separately
Hi Roy,
Unfortunately we don’t sell exhausts – we focus on writing about motorcycles and products for the time being. You best bet might be to contact Harris Performance https://www.harris-performance.com/ , although they no longer appear to be listing exhausts of their own that I could see, only Akrapovic products…
So the alternative would be either finding one secondhand online, something compatible from another supplier, or even building your own…
Hi I’m looking for a Harris works collection for my 1985 GSX1100 Ef is this something you could supply please..

Chris
Can you make a 4 into 1 straight pipe for a Z1000r 1984?
