As most of you know, both precats ( the ones off the manifold) and the down stream cats are prone to failure, mainly the Precats and they are VERY expensive if bought from Nissan. The secondary cats that are easily seen on the Pathy are not metered in any way so removing them would have ZERO impact on the cars ECU or it's fuel mixtures.
Our Ypipe (deletes the unmetered cat)on the FWD VQ35 see gains of 13whp and 14wtq, while our high flow precats see an additional 8hp and 14 tq and feature fully Stainless steel metallic core cats that will not break down like the oem ceramic. AL the while producing a nice G35/FX like sound.
Here is a picture of the FWD version, the ones on the PF are different but it give you the idea. I know the demographic is quite different but at the same time who doesn't want a little extra punch


Anyways let me know your thought and concerns and if the interest is there I'll go the next step and start testing. ( mods if I need to do anything vendor wise please feel free to PM me, but right now this is just a feeler thread)
