RE: hollowed conv.
ORIGINAL: Fox Fader
I've hollowed out a cat on my Bronco back in 2000-01 and 1 1/2 years ago on my Toyota P/U,
it won't hurt the truck at all, but it does give the tunneled sound in that area.ALSO I believe is worse on exhaust
flow than having a properly working cat.
Our cats bolt on right?
If you weld, I'd cut the flanges off and weld them to the proper length/size pipe, bolt it back inand be done with it.
A shop did this on my 300ZX back in '91-92, worked perfect.

RE: hollowed conv.
depends if you have emmisions or not , taking the cat off mite hurt the performance some mite drop the mpg to. when mine was bad i just replace it with a highflow of course in pa we have emission laws . and if you do take it out where are you gonna install the O2 ? need another bung to plug in the pipe..and even if you do that you mite throw a CEL
