Hi,
We are currently running a CBR600F2 in our FSAE racing car, and are considering installing a custom dual exhaust system. It is mostly just due to engine/frame placement and aesthetics, not performance enhancing. My question is, would it be suitable to install 2x CBR600 mufflers, or two smaller exhausts to maintain back pressure?

 

cool thing carry on . but dual exhaust are meant for heavy costum made bikes so be safe
retrofitting

 

Devil and D&D exhausts used to offer a set up like this, they look pretty wicked on bikes and i have seen a number of 600's with them im sure with some retrofitting you could use one of these set-ups and not run into many problems the cans will just be farther apart on your project than they would be on a bike set up like in the pic. You just need to get or make a 2 into 1 adapter to connect to header, or split the header in 2 and run em into 1 on each side so you have 2 true exhausts useing one of those smaller cans per 2 cyclinders, i think you could get it to work just fine with cans like in the pic. but to answere your question yes you can do it but do not use 2 full size exhaust cans. find some like these above they are about half the thickness as a full size since they're designed to use both cans on smaller engine then just have to play with the jets a bit to get the tune right.
