Cat delete

Will taking out the rear cat and replacing it with a pipe cause any problems?

 

Probably worse emissions but it shouldn't throw a code since the o2 sensor is before it

 

Spontaneous combustion












Or not. Might throw a check engine code

 

If you have emissions testing in your state you'll fail, your truck will pollute substantially more and it will sound like shit. Don't really see any benefit to doing it. If you need a new one just go aftermarket, or find one in a junkyard. Much cheaper than OEM.

 

Get a 98 computer and wiring harness and only run one...

Although it would be the lower one lol

Probably easier:

But why

 

Cause BRAP

 

No. no dash lights either.

Just had it done. O2 sensors are on front cats.

 

^^^ idk what these ppl are saying but theres definitely an o2 behind 2nd cat and youl definitely get a cel.

 

Wrong. No cel. O2 sensors on front cats for my 2014.

Also just completed 6500 mile crosscountry wheeling trip. All good. Perfomance improved.

 

get outa here with your 2nd gen

 

You're in the 1st gen forum lol

 

My bad!

Saw the thread title- just had it done!

 

Yeah it seems to get a whole lot more interesting (lol) in the 2ND/3RD gen forums for you 2/3 folks to mingle with us 1St genners. lol

 

I've always curious, Is there a performance improvement if you delete the cat?? If your running a supercharger, I know it's deleted for off road use. The guy that did my cat back said there would
be a 7 percent hp improvement, but I read posts on the internet that there are small differences,
Anyone with real experiences??

 

I can see maybe WoT but being a honeycomb design I can't really see it restricting that much

and someone (@thunderone ) beat me to my favorite meme

 

the piping restricts down to 2.25" with the factory cat tho. hes running smaller pully, fuel mods, and headers so he possibly could see some gains keeping everything 2.5"

 

I'm running a 2" pulley and at 6000 feet, so it is pushing almost 10 pounds of boost, so that's why I was curious

 

Having had my cat stolen a while back and we welded a pipe in till the one I ordered arrived. I did have a cel the entire time without the cat and noticed no difference driving other than the sound change.


For the supercharged guys the performance may change N/A id say no
