Which is the best exhaust size ?
Hello all, I dont know if this question has asked before, I searched but didnt find the proper answer. Which is the best pipe size for my rx 8 headers back exhaust. Some say 76mm (3inch) is best others say this is too much for a N/A engine and 70mm is enough. Does anyone knows which is bestt ?

Back pressure can help you see more torque at certain RPM's but is not needed. Our cars especially don't need any. It is a subject we have talked about a lot but that's basically what I've taken away from it all.
