what was the purpose and/or benefits of an exhaust balance pipe on a V8? It was usually fitted behind the sump and connected the exhaust pipes from both banks.
How does it affect sound, power and torque? Most aftermarket twin systems Ive seen don't bother with a balance pipe. Also, does the shape of the balance pipe have any effect?
cheers frank

Apparently they can aid in the mid range torque of the engine and can make the exhaust note a little more pleasant.
I do not know how all this works but when I rebuilt my HJ GTS the exhaust system that I was replacing had a balance pipe on it and I wan

Hi the reason for having a balance pipe is when the engine fires a pulse goes down the pipe this pulse goes across the balance pipe and up the other side. This pulse gets to the other side when a cylinder is letting out exhaust gas from the other bank of |

That doesn't seem to make sense to me. If the exhaust 'pulse' from one side travels through the balance pipe to the other side, the engine would then have to work harder to overcome the incoming pulse in order to expel the exhaust gases.

its the same principal as extractors, the left bank fires, exhaust gases are pushed through left exhaust, creating vacuum on right exhaust, aiding in the right side being able to expell the exhaust gases from the cylinder with less effort, well thats how |

I see that he means now.
As the gasses pass the cross over pipe they create a vacuum effect through that pipe (and up to the other bank of cylinders) which helps to extract the gases form the other bank of cylinders.

The way I understand it is not so much from a scavenging point of view but more an "overflow" thing. Say a cylinder on the left bank fires no balance pipe & all of the exhaust gases travel down the one pipe (the muffler being the main restriction us Edited by user Sunday, 2 September 2007 8:18:35 AM(UTC)
