hi, i have been told i have got a rare beet exhaust system on my suzuki gsxr400 1989, how do i know if it is a rare beet system is there a way to check, how much would it be worth, and also i am looking to do a full engine rebuild on the same bike but will need gaskets and o rings etc if anybody has any information on who could supply them id be grateful thanks

Is it a gk73a?

Alot of beet systems have balance pipes between the downpipes which the standard system doesn't have, the 73a however does have these as standard so I'm guessing the person who told you it's a beet is probably wrong.

Posting a picture of it may help.

ahh right thanks, there are pictures in the members projects category, thanks

It is deffo a beet system, the stock 73a has yoshi style tubes not simple cross pipes.
You can use Bandi400 gaskets and o'rings.

Did it have twin silencers on it? And if not does it go 4-2-1 but where it splits into 2 there is a pipe blocked off.

I'm only asking as looking at your pics it looks exactly like the stystem I had on mine.

No it didnt have twin silencers on it, i will go back and take some more pictures of just the exhaust to show you more clearly thanks, and the bandit gaskets, what year bandit do you know or is it just the same 1988/1989 thanks

Only one set of gaskets for the bandit and they will fit the 73a.
I will gladly swop my stock twin outlet pipes for your single outlet.

ahh right thanks il look into the bandit gaskets then, and haha id only be willing to get rid of it if it took a large dent out my £3000 credit card haha but thanks anyway.

these are some pictures of the exhaust

Nice...definatly something other than standard.

And in answer to you op....it's only worth what someone will Pay for it.
