Exhaust mod?

sorry if i posted this in the wrong place, still getting use to it. so im redoing my exhaust the cheep way so far i cut out the big drum cat and replaced it with a muffler and kicked it out befor my back tire. my question is will it mess anything up if i cut out the cats on the y-pipe comeing off the manifolds? i mean i will keep the o2 on it just getting rid of the freekin bubbles on the y-pipe.

 

I would keep the cats personally. You won't see any gain removing them unless you are boosted

 

they arent killing flow at all?

 

well its not so much about flow as it is scavenging.

take a look at this thread Chris4x4 made. Very informative
