suggestions for exhaust on ZXR 750 93 for racing.

Wanted - exhaust for ZXR 750 93 pre just a bolt on.. any suggestions on the best type for racing + any jetting that might be required.
The original is way too heavy & the yoshi on my other bike is a bolt on but I dont know the history & therfore dont know if there has been any rejetting.....id have to pull the carbs off to tell & dont have time before my next race meeting.

I'm no Canic mate but i've seen a K&N Air Filter or filter mods balance out an After market Can. So that it didnt need re jetting. I'd pick up any Second hand Zorst Can from a wreckers or Ebay n get a professional to make it fit.
hth. cheers Brett

rob talk to stu hablewaithe at kawasaki southside he has and raced one of 3 factory zxr750's and represented aus in superbikes, he still has his and takes it to the creek every now and then, if theres something to do to ne of those he will be able to help you for sure its the place at bankstown.
hope that helps

roo racing can, aussie made nice & light, good flow,(pontikat reakons u can see my air filter thro mine, i think its a 65mm outlet from memory, str8 thro, yeah baby!!!!) best overall performance when dynoed against the other top brands, check out their site, i think its www. rooracing.com? ohh they're noisy fuggers 2, luv scarin cage drivers as i go past, but i can hold it at around 5000rpm & its relativly quiet. let us kno how u go m8.

Yapa loking at a yoshi RS3 on ebay for 150 clams seems a cheap option + they can be repacked & I can change the internals to suit...
Thanks for the suggestion I remember seeing their pipes arround in the days of tranzac & similar befor the big brands started to be imported.

can't whinge at $150...hope u get last bid m8, good luck
