please help, thanks alot...
as of right now, there are not a lot of options for the c32 to gain power via exhaust. you can do headers.....that will net you the most gains via exhaust. deleting the resonator is mostly for sound, but you will save some weight, probably 10-15 lbs. Deleting secondary cats is also mainly for sound, though you may gain 1-2 whp. I would not mess with your primary cats.....several members went to aftermarket cats and they melted....stick with the stock primary ones.
you may also see slightly gains by switching to the eisenmann muffler, though it is quite expensive
as far as Check Engine Lights (CELs), you will not get one from deleting your resonator and secondaries. if you mess with your primaries, you may get one if not "messed" with properly lol.
I have been told that you may actually see gains by deleting the resonator and secondary cats if you add headers. bottom line: dont delete your primaries
allow me to chime in here please. As for the primary cats you can take them off but you will need spacers for the 02 sensors so that you don't get a code. if you take all the cats off you will see an hp gain but you will haft to get spacers for the o2 sensors in order to avoid any lights from comming on. you can also get let to tune you ecu and have him disable the 2nd o2 sensors so you wont need a spacer on the o2 senors. 2 choices you have ones way cheaper. also check you state laws aswell.
