Stock V6 has an unequal length manifold. Neat sound for a GS, but I'm curious what it would be like without the mic being blown out. Is it all just straight piped off the manifold?
Don't need much math, it'll flow worse than equal. Equal length gives exhaust scavenging across all 4 cylinders. Unequal length gives it across only 2, or potentially zero, depending on setup. It's why many vehicles with unequal length switch to equal length as an easy performance modDid you make it? Or did someone make it for you? Is there any math or flow tests that went into making this or is it just to try to sound cool?
