[DML] Re: Exhaust Back pressure

["content22207" <brobertson@xxxxxxxxxxxx>]

If your straight pipe is attached to the exhaust crossover pipe,
you're still forcing both exhaust streams into a single constricted
outlet.

See Message #43710 (note that our odd firing sequence pretty much
negates the traditional theories).

I'm running true dual exhaust, 2" diameter, no catalytic converters.
Hard to compare directly to a DeLo B28 because I'm also running
different fuel metering (carburetion), but performance shows no sign
of needing improvement.   

Biggest faults with stock DeLo exhaust:
- Extreme heat
- Accessibility (front of the engine as well as the back)
- Restricted flow
