if i cut off 2 of the 4 cats will it thro ne codes or mess up the way the trurk runs like lean or something??? right now i have a weird exhaust it came on the truck it it comes out of the headers into the stock pipe then hits a y pipe and then 2 cherry bombs and turns out behind the tires. it sounds ok i think but i want it to be loader and if cutting the cats off will work and be safe ill do that if not im gonna get the roush im gonna try to get a movie clip tomorrow

 

you can remove the 2 rear cats and should have no problems. you might want to look into high flow cats for the other 2 as this should help your sound too.
