I have an 06 lbz and was told if i remove the cat it will make the turbo spool faster and run better over all.to anyone who has done this is it true?and do any trouble codes come up if you remove it?

I just put on a cat delete pipe and full 4" MBRP exhaust on my '05 LLY and I now have a whole different truck. The turbo spools as soon as you hit the go pedel and the entire truck much better. On my LLY it produced no codes but I think on an LBZ you will need a fingerstick to block the codes. I got a cat delete pipe with a cat back exhaust kit so if I need to put the cat back on for any reason I can quickly reinstall it

I did not get a code when I removed my Kitty. I did when I blocked the EGR. Kennedy finger stick is cheap and you should block the EGR anyway.

Where can i get the fingerstick?

Some of the supporting venders sell them here on the site. Don't worry if you get a code it will not limp the truck-it will just turn on the CEL

No codes for me either. I have the 4" MBRP cat back dual exhaust with cat delete pipe.
