Running a turbo off half of the exhaust
 

So this is my first turbo install on my 99 solara v6 5spd, i had more money then brains at the time and bought a smaller turbo then what i need, question is i had an idea of running the turbo off like a split exhaust so both banks would be going into a single pipe but running a y pipe so only half of the exhaust is being used so it won’t be restrictive
