: 4" Cat back exhaust system LLY 2005 Ringer68 05-22-2005, 07:11 PM Had my cat back cool duals on for a month now. You won"t get any codes with a cat back exhaust. dwrat 05-22-2005, 07:40 PM It depends where your truck came from. Mine is a Arizona truck and I don't get any codes at all with the cat removed and a full 4 inch system. If your truck is from the west coast or east coast you may get a code.:cool: :cool: :cool: Dan LBZ DMAX 05-22-2005, 07:50 PM I had a 4" cat back for about a month with no codes. When my kitten ran away...that's a whole different story. DSTRBD 05-23-2005, 11:27 AM A Cat-back system will not throw codes. EGR codes are thrown when the catalytic converter is removed. Fingers 05-23-2005, 12:22 PM Some people have thrown codes, but not many. Maybe half a dozen that I know of. Go ahead and put them on, you can always get the cure for the codes. aegis 05-23-2005, 01:11 PM I have a Calif truck with magnaflow with catbact and no codes. ssduramax 05-23-2005, 01:35 PM Tuffy, you'll want one of these jewels MBRP cat delete pipe, thanks DSTRBD, easy install and look how much better the exaust flow is compared to the twisted up factory cat pipe. Plus its a 4 inch vs the 3.5 inch factory, more turbo wistle and seet o' the pants meter says better too.:D Mark Craig 05-24-2005, 12:11 PM tuffy, Cat back is not a problem except like Fingers said in some very odd cases. I haven;t had a customer have a light yet on a LLY with a cat back that I know of yet! Mark @ DPPI Liftedhdrado 05-24-2005, 03:06 PM Someone pls educate me on this. I keep on hearing cat and kitty...are those 2 different things or the same thing? what is a kitty?

Dmax Tim 06-07-2005, 09:57 AM Now how much louder is a catback system on a truck with a cat? A waste of time, kill the kitty and go play. BIG MACZ 06-07-2005, 10:18 AM No cat and a 4" on mine, only 1100 miles but no codes yet. toyotasaurus 06-07-2005, 03:24 PM A waste of time, kill the kitty and go play. Would it be of any benefit to kill the kitty with a stock exhaust? | ||
