Hey all, so i just bought an EF Hatch with a JDM B16, i'm stoked! but first i'll tell you that the exhaust is disconnected right after the headers and before the cat. i was driving down the highway and my motor just started losing power and made a wierd bogging noise. could this be happening purely because of my lack of exhaust or back pressure? it starts fine but runs and idles really rough. any suggestions are greatly appreciated!! thanks

 

make sure your two o2 sensors aren't wired to each others plugs. this seems to happen alot.

 

ya i would guess that as well. i had the same issue
