flexpipe in place of resonator?

i want to get rid of my resonator/pre-silencer and was wondering if i could use a piece of flexpipe in it's place? would i be better off just getting a piece of regular pipe to put in it's place? which way would be cheaper? also, since i have stock exhaust piping, should i get a 2" pipe, that way it should slip right on to the stock piping right?

flex pipes aren't cheap , especially one that long. Piping is cheap.

if your having a shop do it, they'll just flair the ends to slip over the stock pipe. If your doing it, a 2" ID pipe might slip over 1 7/8 ID pipe, not sure.

How much of a difference would it make? Would it still smog? I noticed that if I give a couple of taps to my resonator you hear a sound, I guess like pebbles in a box or whatever, well the ceramic pieces rattling around. So basically it's shot I suppose...just curious what it would do to remove it. I was searching for this but there is a thread right here on it!

it's gonna make the exhaust louder. anyone think it will gain a hp or two? i'm also not sure about the smog part. hopefully someone with more knowledge on exhaust stuff can help us both out.

so are you going to be replacing the cat or the resonator...
Well the one that I was talking about was the one closer to the muffler...

I thought that was the resonator...
