I just replaced the exhaust system on my Super ES. The new system is larger both in primary and collector sizes. Seems to work just fine.
When installing it, I made sure to locate the EGT probes in the same location as on the earlier models (within a 32nd or so, anyway).
Question: Why are my EGTs now averaging 100 degrees cooler than before? Am also using marginally more fuel.
Are the new pipes flowing better and therefore not keeping the hot exhaust in the system as long as before? Can the new pipes be enough better to be producing a bit more power, thus the need for more fuel?
Would appreciate any input. Don't see any of this as a problem just want to know what happened.
Thanks,
