I tried using logic on this one...

Lately there has been much speculation about and O/r X losing hp due to the lack of back pressure. now it isnt really backpressure we want its like delta pressure i dunno, thats an entire other thread somewhere.

Also- a side exhaust system is supposed to increase back pressure and you lose some HP.

so if you paird an offroad X (supposed to lose back pressure) with a side exhaust (extra back pressure) wouldnt they balance out and actually give you more hp somehow?

example (assume all these cars are exactly the same and dynoed the same etc.)

car 1- side exhaust+ off road X
car 2- side exhaust+ catted X
car 3- regular exhaust+ off road X
car 4- regular exhaust+ catted X

would car 1 have the most hp?

im not worried about it for my specific set up i was thinking about it hypothetically- actually iwas thinking about it during class and it seemed interesting enough to post.
