Any tried or thought of going direct port and boring the nitrous nozzles into one of the aftermarket plenums? Comments.

Also, do aftermarket cats reduce your EGT's when spraying?

Thanks.

 

Exhaust Gas temps should be measured before the cats, thus aftermarket cats should have no effect.

Sorry, no help on the first question.

 

EGT's are measured before the cats, but I heard restrictive cats cause heat buildup because of the pressure. Free flowing cats let the exhaust travel out easier, therefore, less pressure, therefore, less heat.

Someone told me to look into getting aftermarket cats to keep EGT's lower especially running my 150-shot.
