Going to start this project soon. I acquired an r1 undertail exhaust. I am only going to use the right side can , and try to fabricate it up to the stock cans position. I figure it should not be overly loud being as how its made for 1/2 the 1000cc bike. Its made of titanium so its light. Down the road I want to get the drz E head pipe on there as well , But hey I figure it will make a nice inexpensive light exhaust. I will keep you posted on the progress.
