You can't find them because the bike is 17 years old. All manufacturers stopped production a long long long time ago.

Only places you will find something will be ebay, craigslist and best of all our parts for sale section. :fact

 

I have a Muzzy 4 into 1 stainless system that is in very good condition with a polished aluminum can. I had it on my 99 R1.

 

Skysthelimiter should jump on this..... if he does not i might be interested he might prefer this one that im running. Yoshi 4-2-1 with balance pipes. great for low to mid grunt road race type application. where yours (correct me if im Wrong) is more suited for top end drag type application?
I would be keen to do a deal if all the numbers add up

 

Apology accepted. And sorry if I jumped down your throat. Was feeling a little butthurt! Both systems have pros and cons depending on what application you want them for.

 

There are UK and Italian companies still making full systems. Black Widow in the UK, although they may have rebranded, and GPR in Italy.

 

I would agree with sconeroll that 4 into 1 is preferred for top end power and 4-2-1 will improve the mid-range more than 4-1. But my experience with the Muzzy, was improvement over stock system thru out the rev range. I never put it on the dyno, so I have no hard numbers. Years ago, I know Ivan tested exhausts on the early R1s and his best HP numbers were with 4-1 and only Akra and Muzzy made them. He developed and sold jet kits for 4-1. Just a side note, it sounds real nice at high rpms.

 

Thanks guys for your responses. Yea I kinda figured with the bike being so old it would be hard to find new full exhaust. I?m not much of a racer I just enjoy riding around town. So I don?t need anything special. I bought the bike for 1000$ with only 14k on the bike. Needs a lot of cosmetic work,but mechanically it?s in great shape other than some electrical/charging issues. Only reason I want a full exhaust is I have the exup rpm code and I don?t feel like fixing the exup server, so i rather just switch it to a full exhaust. I?m interested in anyone?s used exhaust, just let me know prices and send some pics. Thanks

 

And I do prefer 4-1 over 4-2-1

 

Interesting thread. I did not know that Muzzy made a 4-1 for the R1.

 

Here is a pic

 

The can looks just like the ones that were on my ZZR1200 - great fun to keep looking good! Is the system for sale?

 

Yes, i would sell it. I've had it in the basement for a few years.
