newbie to the forum and have done lot's of research on the this board. until i searched around i didn't quite appreciate how much info is here. thanks to all.

it appears removing stock cats and adding high flows can be done. does anyone have before and after pic's of the process.

if not, i could use a little more detailed description of how this is done. i realize you may not need all of the o2 sensors and welding is needed. any
help would be appreciated.

the can cut, the muffler shop that is, right after the first o2 sensor, to the other one. add pipe to the maggie high flow then weld it where the two were on either side. i still have all four o2 sensors. i recommend having them from the manifold, fabricate a set up to a custom y pipe then after the y pipe to the rest of the exhaust. i already had a cat back do they hooked it up to that
