It's a nice smooth power band all the way through.
Pato - good to see you featuring in the podiums. Keep up the good work.
central hole of second chamber is closed 10mm for GO 0801 and GO 2072.
but GO 2047 is more bigger than 0801,2072 to 13mm.
if central hole bigger than 10mm,the power band is between at top to mid. then noise is more too.and fuel consumption is more too.
if central hole average at 10mm,the power band,noise,fuel consumption are conform to IFMAR rules.
so each tuned pipes have different set up to GO TECH engine.it's depend on your favor.
