The exhaust I had fitted originally was a pretty cheap system to get me through compliance. Job done!

Want to look at rebuilding the system to develop a nice note without being overly raucous and keen to get some ideas on sizing.

Running a standard 5L Windsor as the 220kw variant with headers taken from an RMC and the standard AU cats for the model at the time.

Just to make it be a nice street car.

So what is the suggested sizing from the headers through to the rest of the system?

And while I'm asking what does a balance pipe achieve linking left and right exhaust banks?

The one future plan I might explore, though a long time off, is supercharging the motor, how does this affect exhaust sizing?

Cheers
