U should be ok..but replace both of em ...i have pypes hiflow
thats what he has...
interesting thought though, how do the different pressures affect the engine, one side of the engine might have an increased wear than the other half.. short term it shouldnt hurt badly.. but i wouldnt do it for more than a couple months.. werent you talking about swapping to magnaflow cats anyway since the pypes are circular and give less ground clearance
