any body cut there cats off what was the result as far as power and noise

 

No gain at all,most cars will loose power without it..

 

is it cause of the a/f ratio if so will a piggy back fix this

 

Go for it..

 

would it run rich or lean?...

 

It will run rich.

Sound is slightly diffrent.

Get a test pipe / fast cat from CP. For those just incase scenarios when you need to pass emissions later on.

I'm running CP Y-pipe 2.5" exhaust w/out cat. it smells...just so you know.

 

running y-pipe w/test pipe. you cant feel it but track times show a small improvement. no smell problem here, just smells like it shoud...not clean

 

I saw a gm/s increase @ higher RPM w/o it.

 

u'll get 1-2hp from taking off your cat for a test pipe;
worth it?

 

Well, I tried cutting my cats once, I got clawed.

Don't do it...

 

I don't think the added pollution and having to pay for an inspection ticket makes it worth 1-2 hp. Get something else that'll get you more hp and less headaches!!

 

like a turbo

 

well i dont have to worry about emissions in florida

 

nor do we in arkansas

 

Nor NM...>..>

 

I am using a test pipe, then for emissions pop my cat back on.

 

sadly, i would be willing to bet that you can pass emissions without the rear cat as long as the precats are still installed/working. obviously headers/test pipe wont pass. but really it might not fail by much. cars run real clean these days
