Exhaust help!!

[davemwhite88]

Im looking for some answer's with exhaust modifications.

And my question is i have a 4 cyclinder 600cc sports bike, it currently has a 4 into 2 into 1 header pipe with a link pipe to muffler on the right side, and was thinking about fabricating a split link pipe so i have another muffle on the left side ( so dual exit exhaust), the link pipe is 51mm from the collector and not sure if i have to split with the same size pipe or go smaller on it.

i believe the collector part does all the back pressure for scavenging and stuff but after that id like to change it would i have to change these pipe sizes or atay the same.

thanks in advanse Dave

Just buy a recent ish GSXR thou and be done with it, what you propose will most likely make little difference to the running of the bike, and surely you'd have to use the same diameter pipe for aesthetic reasons, its your bike to do as you please, I don't know why you'd want to add extra weight hanging off the side of the bike but each to their own, a 600 doesn't need twin exhausts.
