i was wondering if cutting the cats off and replacing them with pipe would do anything for me? some poeple say it'll stink but i can deal with that, and will i have any trouble with the rear o2 sensors?

 

Yes it can be done, yes it will smell, yes it will cause a SES light to come on lol.. Best bet is to have it retuned, or search for my thread(long time ago) on plug defoulers... THEY WORK

alright i'll look that up. will i feel any difference in power though?

 

It'll be louder and seem like more power!

 

If it doesn't make more power then why do so many people toss the cats?

 

The sound. It might free up a lil bit of power

i ran a 00 silverado 5.3 with no cats and now run hi-flow magnaflow cats. seems the same to me. but it was a helluva lot louder without the cats

 

Depends on what other mods and horsepower level I'd think. On a NA fairly stock setup you'd probably not notice much.

 

I don't see the point in chopping up the stock Y pipe myself. You'll hardly feel any gains, if at all and you'll no longer be able to pass emissions. I have the pacesetters and catless Y, but if I had money burning a hole in my pocket I would add some magnaflow center spun metallic cats.

 

To be honest, I might get high flow cats on my next set up and just run them, no muffs
