Something tells me the two mods together don't necessarily offset the losses in a simple arithmetic type of way for an overall gain. Can anybody explain what to expect from the combination of two mods of this type either from a seat of the pants perspective or with dyno charts?
Further, I have high flow cats. At what point does this car have too LITTLE backpressure? If ever?
Thanks in advance.

saying it short and simple.
it all come down to optimizing the airflow capabilities of your mods.
bigger doesnt always mean better ,
doesnt mean its big and it will result in less restriction,
an exemple for this is your exhaust ,,,
too big of an exhaust, your airflow will slow down considerably before it leave the tailpipe. this also create backpressure
which you want to avoid as much as possible if you are staying N/A and want the most power in the higher powerband.
once you have a good flowing exhaust you have to find where is the bottle-neck. which will surely be on your intake side.
