will run you OVER
from the front:
OBX SS long tube headers
resonators (look like cats)
goes back to dual Badlanz SS electric cutouts
MAgnaflow SS X-pipe
Dual Borla XR-1 Race muffler
currently I just have tips after the mufflers, previously I had it tipped Lightning style, but with traction bars I had to remove them

Here's my Super 44 with all 4 cats. It sounds pretty good in this video, but that's cause the camera is right next to the exhaust. I guess I just want something louder.

you gotta remember that cutting off the cats could cause a MIL to appear and could cause some gas mileage issues, possibly others.
the o2 sensors send signals to the computer to tell when the exhaust is at the proper temp and what the o2 content of the exhaust is, whether rich or lean. the o2 sensor can affect the fuel/air ratio that is being pushed into the engine which is needed for proper combustion.
this may or may not affect the EGR valve as well (cant remember if the EGR gets its info from the o2 sensor or right from the combustion chamber) which helps with the amount of HC and NOx exiting the combustion chamber, could end up pushing even more HC and NOx out of the exhaust which the cat is supposed to filter them hydro-carbons and NOx but since it aint there theyre going right past it. thus, the reason we have cats.
my point is that it could affect your gas mileage by choppin cats. that o2 sensor is somewhat important.
correct me if im wrong though!
