Hi guys, i have a supercharged 1uz (Eaton M112) and am wondering the advantage of a balance pipe on a dual exhaust system, as in do i need a balance pipe or not?
The advantage depends on a number of factors, including balance pipe placement
As a rule of thumb, the preformance is usually better with balance pipe of some sort than without one
Im going to have it put back as it was, two into one then split into two again for no other reason but the sound, its louder now and not as nice/crisp as before.
